<strong>Plummer</strong> Block and Rolling Bearing Tolerances<br />

2.2 Machining tolerances of mounting bolt seat<br />

faces<br />

When subjected to a greater lateral load, a plummer block<br />

cannot be reliably secured with the tightening force of<br />

mounting bolts alone. To overcome this problem the end<br />

faces of the mounting bolt seat are secured with stoppers<br />

to lock the plummer block. With the plummer block used<br />

in this type of application, the end faces in contact with<br />

the stoppers are machined.<br />

When a plummer block mounting seat end faces have<br />

been machined, the bottom length L of the bearing<br />

housing is smaller by the dimension in Table 2.5.<br />

<strong>Plummer</strong> Block and Bearing Materials<br />

3. <strong>Plummer</strong> Block and Bearing Materials<br />

3.1 <strong>Plummer</strong> block materials<br />

The housings of <strong>NTN</strong> plummer blocks are made of class 3<br />

gray cast iron (FC200). Table 3.1 summarizes the<br />

mechanical properties of this material.<br />

Cast iron materials boasts the greatest vibration<br />

dampening capability among various metal materials.<br />

They also perform well in a wider operating temperature<br />

range of –20 to 300˚C.<br />

For application involving shock load and vibration, class 2<br />

spheroidal graphite cast iron (FCD450) or class 3 carbon<br />

cast steel (SC450) is used.<br />

3.2 Bearing materials<br />

Raceway and rolling element materials<br />

When the contact surfaces of a bearing raceway and<br />

rolling elements are repeatedly subjected to heavy stress,<br />

they still must maintain high precision and running<br />

accuracy. To accomplish this, the raceway and rolling<br />

elements must be made of a material that has high<br />

hardness, is resistant to rolling fatigue, is wear resistant,<br />

and has good dimensional stability.<br />

By using pure materials, low in these non-metallic<br />

impurities, the rolling fatigue life of the bearing is<br />

lengthened. For all <strong>NTN</strong> bearings, pure material is<br />

prepared which has low oxygen content and low nonmetallic<br />

impurities, by vacuum degassing process and<br />

secondary refining process.<br />

Cage materials<br />

Bearing cage materials must be strong enough to<br />

withstand the vibration and shock load occurring on<br />

running bearings, develop limited friction with rolling<br />

elements and bearing ring, be light, and resist the heat<br />

occurring on running bearings.<br />

The cages for small- and medium-sized bearings are<br />

pressed cages prepared through pressing process with<br />

cold or hot rolled steel plate, while the cages for largesized<br />

bearings are machined cages made of cast high<br />

tensile brass or carbon steel for machine structural<br />

purposes.<br />

Strength of <strong>Plummer</strong> <strong>Blocks</strong>, and Combination with Bearings<br />

4. Strength of <strong>Plummer</strong> <strong>Blocks</strong>, and Combination with Bearings<br />

4.1 Strength of plummer blocks<br />

The disruptive strength of plummer block varies<br />

depending on its type, nature and direction of a load<br />

working on it, as well as the flatness of a surface to which<br />

it is installed. The typical trend of static disruptive strength<br />

of SN5 and SN6 (S6) series of cast iron plummer blocks<br />

is plotted in Figs. 4.1 and 4.2 respectively.<br />

When selecting a plummer block, the safety factors in<br />

Table 4.1 must be considered. Also, a higher grade of<br />

flatness is required of a surface for mounting a plummer<br />

block.<br />

Allowable Speed<br />

5. Allowable Speed<br />

Greater bearing speed leads to higher bearing<br />

temperature owing to friction heat occurring within the<br />

bearing. When the bearing is heated beyond a specific<br />

limit, a bearing failure such as seizure occurs, and the<br />

bearing cannot maintain stable operation any more. The<br />

limiting bearing speed where a bearing can operate<br />

without developing heat beyond a particular limitation is<br />

called allowable speed (rpm). This varies depending on<br />

the type and size of bearing, type of cage, as well as<br />

loading, lubricating and cooling conditions.<br />

The bearing tables in this brochure summarize the<br />

typical allowable bearing speeds either with grease or oil<br />

lubrication. However, these values assume that:<br />

¡An <strong>NTN</strong> standard design bearing having correct internal<br />

clearance is correctly installed.<br />

¡The bearing is lubricated with quality lubricant, and the<br />

lubricant is replenished or replaced at correct intervals.<br />

¡The bearing is operated under normal loading<br />

conditions (P0.09Cr, Fa/Fr0.3), and at a normal<br />

operating temperature.<br />

Note, however, that rolling elements may fail to rotate<br />

smoothly under a load of P0.04Cor. For advice against<br />

this problem, contact <strong>NTN</strong> Engineering. Also, note that<br />

the allowable speed of deep groove ball bearing having a<br />

contact seal (model LLU) or low-torque seal (model LLH)<br />

is governed by the peripheral speed of the seal. The<br />

allowable speed of a bearing that is used under severe<br />

operating conditions can be determined by multiplying the<br />

allowable speed of that bearing in a bearing table by an<br />

adjustment factor in Fig. 5.1.<br />

The allowable speed of a plummer block with a bearing<br />

varies depending on the seal type used. For example, in<br />

the case of a plummer block having a contact seal, its<br />

allowable speed is restricted by the allowable peripheral<br />

speed of the seal. Fig. 5.2 provides a guideline for<br />

selecting allowable peripheral speeds of various seals.<br />

Bearing Seals<br />

6. Bearing Seals<br />

The purposes of bearing seals are to prevent lubricant<br />

from leaking out and to protect the bearing against<br />

ingress of dust and moisture.<br />

An appropriate bearing seal is selected considering the<br />

lubricant type (grease or oil) and the peripheral speed of<br />

the seal.<br />

The seal type of <strong>NTN</strong> plummer blocks can be either<br />

contact or non-contact type. The contact type is available<br />

as felt seals and rubber seals, while the non-contact type<br />

as labyrinth seals. Also, special combination seals are<br />

available for applications under severe operating<br />

conditions involving, for example, heavy air-borne dust.<br />

6.1 Contact seals<br />

(1) Rubber seal (Fig. 6.1)<br />

Rubber seals are typically used for grease lubrication,<br />

and their allowable peripheral speed, as a guideline,<br />

ranges from 5 to 6 m/s.<br />

Usually, the material of rubber seals are nitrile rubber.<br />

However, to cope with demanding ambient temperatures,<br />

the materials in Table 6.1 are also available.<br />

(2) Felt seal (Fig. 6.2)<br />

Felt seals are compatible with rubber seals, but must be<br />

used for grease lubrication only.<br />

Felt seals are not suitable for dusty or moist<br />

environments. Their allowable peripheral speed, as a<br />

guideline, is 4 m/s max. A felt seal can be cut into two<br />

pieces that are respectively fitted into the seal grooves on<br />

the upper and lower plummer block housings. This<br />

feature greatly simplifies the assembly procedure for<br />

plummer blocks.<br />

Nitrile rubber (NBR) 25<br />

100<br />

Nitrile rubber (NBR) resists virtually all oil types and also features good wear<br />

resistance. Thus, this material is most commonly used as an oil seal material.<br />

It can be used in ordinary machinery operating under virtually any normal<br />

operating conditions.<br />

Silicone rubber (VMQ) <br />

Fluororubber (FKM) <br />

<br />

Boasts excellent heat resistance and oil resistance, but is rather vulnerable<br />

to alkali or water. Thus, the scope of its applications is limited.<br />

Boasts excellent heat resistance and cold resistance. However, it cannot be<br />

used together with extreme pressure grease or spindle oil.<br />

Inert to virtually all oil or chemical types. Its properties are well balanced.<br />

Therefore, it features wider operating conditions range. To sum up, this is<br />

a superior oil seal material.<br />

Bearing Seals<br />

(3) S grease seal (Fig. 6.3)<br />

The S grease seal (synthetic rubber seal with spring)<br />

excels in sealing performance and is well suited for<br />

grease or oil lubrication. Custom specification variants<br />

can be used in a plummer block.<br />

Its recommended peripheral speed falls within a range<br />

of 10 to 12 m/s. The surface roughness and hardness of<br />

the shaft in contact with this sealing material necessitates<br />

special attention.<br />

Fig. 6.5 Special labyrinth seal<br />

Shaft design specification for the area in contact with the seal<br />

The quality of a shaft section in contact with the seal lip<br />

greatly affects the sealing performance of the seal.<br />

Therefore, strictly adhere to the design standard for<br />

shafts in Table 6.2.<br />

Table 6.2 Shaft design standard<br />

6.2 Non-contact seals<br />

(1) Labyrinth seal (Fig. 6.4)<br />

The labyrinth seal used in the bore of plummer blocks --<br />

SD31TS and SD32TS series-- comprise a labyrinth<br />

ring that is fitted into the bore of the plummer block. A<br />

labyrinth seal is used in clearance fit to a shaft (h9)<br />

together with an O-ring so that it can be readily installed<br />

and can follow expansion/compression of the shaft.<br />

This seal type excels in sealing performance, and can<br />

be used for grease or oil lubrication.<br />

6.3 Combination seals<br />

The combination seals used for the SBG series are<br />

unique seals that comprise both of an oil seal and<br />

labyrinth seal and are installed in the bore of a plummer<br />

block. They are used in environments where heavy dust<br />

and contaminants are present.<br />

For better sealing effect, the labyrinth seal is often filled<br />

with grease.<br />

Fig. 6.4 Labyrinth seal<br />

(2) Special labyrinth seal (Fig. 6.5)<br />

The special labyrinth seals such as those in Fig. 6.5 are<br />

very useful for applications where heavy soil and dust are<br />

present.<br />

The plummer blocks used in conjunction with this seal<br />

type are manufactured per custom specifications. For<br />

further information, contact <strong>NTN</strong> Engineering.<br />

With a continuous or intermittent lubrication<br />

scheme, lubricant can tend to leak. Use a seal<br />

that positively offers reliable sealing.<br />

Shaft Design<br />

7. Shaft Design<br />

7.1 Bearing-to-shaft fit<br />

The tolerance requirements of the shaft outside<br />

diameter differs between a bearing with an adapter and a<br />

cylindrical bore bearing each mounted to a plummer<br />

block. Table 7.1 summarizes the recommended bearingto-shaft<br />

fits.<br />

A bearing with an adapter is installed to a shaft by<br />

means of an adapter. A cylindrical bore bearing is usually<br />

positioned in interference fit by a shaft shoulder and<br />

secured with a nut and washer. For this application, the<br />

shaft is provided with threading and washer groove as<br />

illustrated in Fig. 7.1.<br />

7.2 Mounting dimensions<br />

To be able to correctly seat a cylindrical bore bearing to<br />

the shaft shoulder, the height and fillet radius ras of the<br />

shoulder must be greater than the chamfering rs min of the<br />

bearing as specified in Table 7.2.<br />

If the bearing is used on the shaft end, the configuration<br />

must be designed such that the shaft end does not<br />

interfere with the face of bearing bore. For reference,<br />

Table 7.3 provides the wall thickness values at the<br />

bearing bore.<br />

Grease lubrication leads to good sealing performance<br />

and simpler seal design.<br />

(1) Characteristics of grease<br />

Grease is prepared by mixing base oil such as mineral<br />

oil or synthetic oil with thickener. The characteristics of<br />

grease vary depending on types and combination of<br />

various additives.<br />

The typical grease types and their characteristics are<br />

summarized in Table 8.1.<br />

Depending on the intended application, a grease of<br />

appropriate consistency number is used as summarized<br />

in Table 8.2.<br />

(2) Grease volume<br />

When grease is packed into a bearing, the inside of the<br />

bearing is first filled with grease. During this course, the<br />

grease must be also filled into the inside guide way of the<br />

bearing cage.<br />

As a guideline, the recommended volume of grease<br />

filled in plummer blocks is given below.<br />

General application<br />

⋯⋯⋯⋯About 1/3 to 1/2 the empty space<br />

Relatively high speed application<br />

⋯⋯⋯⋯⋯⋯⋯About 1/2 the empty space<br />

Low speed application<br />

⋯⋯⋯⋯⋯More than 1/2 the empty space<br />

The volume of grease should be carefully selected as it<br />

can lead to overheating of the bearing, outward leakage<br />

from the seal, or ingress of dust.<br />

The recommended volume of grease commonly filled in<br />

the applicable bearings are summarized in Table 8.3.<br />

Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

9. Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

Rolling bearings are precision components. To maintain<br />

their accuracies, they must be handled very carefully. In<br />

particular, they must be kept clean, not be subjected to<br />

strong impact, and be protected against possible rusting.<br />

<strong>Plummer</strong> blocks also need similar handling practices.<br />

9.1 Inspection before installation<br />

Before installing a bearing and a plummer block, the<br />

following points must be thoroughly checked and<br />

inspected.<br />

(1) Prepare installation tools, measuring instruments, oil<br />

stone, lubricant and factory cloth. Before the<br />

installation work, remove dust and impurities from<br />

these tools. (Fig. 9.1)<br />

Fig. 9.3<br />

(5) Check the flatness of the mounting face of the<br />

plummer block. (When placed on a frame, the<br />

plummer block must be stably seated.)<br />

Fig. 9.1<br />

(2) Make sure that the shaft is free from bends or other<br />

damages and that it has been dimensioned and<br />

formed as specified. (Fig. 9.2)<br />

9.2 Preparation for installing the bearing<br />

(1) Unpack the bearing just before the installation work.<br />

(2) If the bearing is to be grease-lubricated, the rustproof<br />

coating on it may remain unremoved. If it is to<br />

be oil-lubricated, remove the coating with benzene<br />

or kerosene.<br />

(3) For a bearing with an adapter, check its radial<br />

clearance before the installation work. To do so,<br />

place it on a flat work bench, and fit a thickness<br />

gage between the uppermost roller and the raceway<br />

surface on the outer ring to measure the clearance<br />

(Fig. 9.4). Do not force the thickness gage in or turn<br />

the bearing. Otherwise, the resultant clearance<br />

measurement will be greater than the actual<br />

clearance.<br />

Fig. 9.2<br />

(3) Remove dent marks (even though very small) from<br />

the mating faces with an oil stone or fine emery<br />

paper. Check that the contact face to the seal has<br />

specified surface roughness (0.8a). Wipe dust away<br />

from the shaft with clean factory cloth.<br />

(4) Remove possible dust and metal chips from the<br />

inside of plummer block. (Fig. 9.3)<br />

Fig. 9.4<br />

Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

9.3 Installation of the bearing and associated<br />

components<br />

Once careful checking is complete, install the bearing<br />

and associated components. For the positional<br />

relationship, see Fig. 9.5.<br />

Fig. 9.6<br />

Fig. 9.5<br />

When a bearing is installed onto a shaft or into a<br />

housing, do not directly hit its end face with a hammer<br />

or drift as shown in Fig. 9.6. Otherwise, its design<br />

performance can be lost. Always evenly exert force<br />

around the entire bearing ring face. Also, do not apply<br />

force to one bearing ring (for example, outer ring) as in<br />

Fig. 9.7 to convey the force via the rolling elements to<br />

the other bearing ring (inner ring) to install the latter.<br />

Otherwise, a dent mark or other damage can occur on<br />

either or both rings.<br />

Fig. 9.7<br />

When installing a cylindrical bore bearing, whose<br />

interference is relatively small, its whole inner ring can<br />

be uniformly press-fitted at an ordinary temperature as<br />

illustrated in Fig. 9.8. Usually, the inner ring is pressfitted<br />

by tapping the sleeve with a hammer. However,<br />

when many bearings must be installed at a time, a<br />

mechanical or hydraulic press will be helpful.<br />

When installing a non-separable bearing to the shaft<br />

and housing at a time, apply a press-fitting force to<br />

both the inner and outer rings by using a pressure<br />

distribution pad as in Fig. 9.9.<br />

Fig. 9.8 Press-fitting the inner ring<br />

Fig. 9.9 Simultaneous press-fitting of the inner and outer rings<br />

Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

9.3.1 Bearing with an adapter<br />

(1) Thinly apply highly viscous mineral oil to the taper,<br />

threading and the chamfered face of the nut (see<br />

Fig. 9.10) before press-fitting. In particular, apply<br />

molybdenum bisulfide paste to these areas on a<br />

large bearing. This prevents scuffing, and allows<br />

easy bearing removal. Before the installation work,<br />

remove oil from the shaft and the bore face of<br />

sleeve with a clean factory cloth.<br />

the slit with a flat-blade screwdriver for easy fitting.<br />

FIg. 9.11<br />

Fig. 9.11<br />

Fig. 9.10<br />

(2) Mount the adapter to a correct position considering<br />

the dimension B1, B2 or B3 in the bearing table.<br />

When fitting the adapter sleeve onto the shaft, open<br />

(3) Fit the bearing over the adapter sleeve on the shaft<br />

as tight as possible, so that the bearing inner ring is<br />

fully seated onto the taper on adapter sleeve.<br />

(4) Lightly tighten the nut until the sleeve is seated on<br />

the shaft.<br />

(5) When fully tightening a self-aligning ball bearing,<br />

make sure that its radial clearance becomes<br />

approximately 1/2 that before fitting. For a selfaligning<br />

roller bearing, tighten the nut while<br />

measuring its radial clearance with a thickness gage<br />

so that the reduction of radial internal clearance<br />

value in Table 9.1 is reached. Make sure that an<br />

installed self-aligning ball bearing can turn smoothly<br />

by hand (ss Figs. 9.12 and 9.13).<br />

Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

(7) If it is difficult to tighten a large bearing by manual<br />

force, use a hydraulic nut or ram for easier<br />

assembly. (See Fig. 9.15.)<br />

Fig. 9.12<br />

Fig. 9.15<br />

(8) Make sure the bearing clearance is as specified,<br />

then bend one tab on the washer that corresponds<br />

with the cutout on the circumference of the nut to<br />

maintain the adjustment (Fig. 9.16). Do not loosen<br />

the nut to allow the cutout to match the tab.<br />

Fig. 9.13<br />

(6) To tighten the nut, use a spanner wrench illustrated<br />

in Fig. 9.14.<br />

When tightening the nut with a hammer and a drift,<br />

be sure that the chip from the drift does not enter<br />

the bearing.<br />

Fig. 9.16<br />

(9) When a large bearing is installed to a shaft, its outer<br />

ring will be deformed by its own weight into an<br />

elliptical form. The clearance measurement at the<br />

lowest point on a deformed bearing will be greater<br />

than a true clearance. Remember that a radial<br />

clearance value measurement at this point will result<br />

in excessively large tightening allowance.<br />

Fig. 9.14<br />

(10) The adapter used on a large bearing whose bore<br />

number is 44 or greater is a lock plate type (Fig.<br />

9.17). For this arrangement, first tighten the nut,<br />

then fit the lock plate into the cutout on the nut. In<br />

this case too, do not loosen the nut to allow the<br />

cutout to match the lock plate. Once the lock plate is<br />

seated in the cutout, secure the adjustment with a<br />

spring washer and a hexagonal nut.<br />

Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

Fig. 9.17<br />

9.3.2 Cylindrical bore bearing<br />

(1) Press-fitting<br />

a. It is recommended that a small bearing of smaller<br />

tightening allowance be press-fitted by forcing a<br />

press-fitting jig onto the end face of inner ring.<br />

(See Fig. 9.18.)<br />

Fig. 9.19<br />

d. After fitting the bearing onto a shaft, allow it to<br />

cool off. Note that the bearing will also shrink in<br />

the axial direction. To avoid gap occurrence<br />

between the bearing face and the shaft shoulder,<br />

force the bearing against the shaft shoulder until<br />

the bearing and shaft have fully cooled down.<br />

Alternatively, tap the bearing several times in the<br />

axial direction through a jig to bring the bearing in<br />

close contact with the shaft before the bearing<br />

and shaft have fully cooled down.<br />

Fig. 9.18<br />

b. For easy fitting, apply mineral oil or molybdenum<br />

bisulfide lubricant to fitting surfaces on the shaft<br />

and bearing. During the press-fitting work, make<br />

sure that the bearing inner ring is not tilted.<br />

(2) Shrink-fitting<br />

a. To install a medium or large bearing, a shrinkfitting<br />

technique can be conveniently employed.<br />

The heating temperature for shrink-fitting can be<br />

selected from Fig. 9.19 based on the bearing<br />

dimensions and tightening allowance<br />

requirements. Remember the temperature of the<br />

bearing must not exceed 120˚C.<br />

b. Usually, the bearing is heated in oil (Fig. 9.20).<br />

However, it may be heated in a heater.<br />

c. The oil used as a heating medium is clean<br />

machine oil #1 or transformer oil #1.<br />

The heating oil bath must be amply sized and<br />

contain sufficient amount of oil. Be careful not to<br />

allow the bearing to directly contact the vessel.<br />

Fig. 9.20<br />

e. Make sure the bearing is fully seated on the shaft<br />

shoulder. Then, insert the washer and nut over<br />

the shaft, and secure the bearing by tightening<br />

the nut. Once the nut has been fully tightened,<br />

bend a tab on the washer and fit it into the cutout<br />

Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

9.4 Assembling the plummer blocks<br />

When installing two or more plummer blocks on a shaft,<br />

use one block to locate the outer ring of a bearing in the<br />

axial direction, and arrange the other block (s) so that the<br />

outer ring (s) of bearing (s) in the latter block (s) can<br />

move freely in the axial direction. (See Fig. 9.21.)<br />

Once the bearing has been installed to the shaft and the<br />

associated components have been inserted over the<br />

shaft, assemble the plummer blocks according to the<br />

following procedure.<br />

Fig. 9.23<br />

Non-locating side<br />

Locating side<br />

(3) Adjust the position of the plummer block of the nonlocating<br />

bearing to center the bearing to the bearing<br />

seating.<br />

If the plummer block is to be used in a high temperature<br />

environment, carefully position the bearing considering<br />

the thermal expansion of the shaft.<br />

Locating side<br />

(with one stabilizing ring)<br />

Fig. 9.21<br />

Locating side<br />

(with two stabilizing rings)<br />

(4) Once the bearing is correctly located, check the<br />

squareness of the plummer block relative to the<br />

shaft (make sure the face of bearing inner ring is<br />

parallel with that of the outer ring). Only then, fully<br />

tighten the nut. Remember a larger mounting error<br />

can cause the seal to fail or the shaft to interfere<br />

with the bearing bore, leading to non-smooth<br />

running (Fig. 9.24). If such a problem occurs,<br />

correct the mounting seat, and then, install the lower<br />

plummer block housing.<br />

(1) Temporarily install the lower plummer block housing<br />

to the frame. (See Fig. 9.22.)<br />

Fig. 9.22<br />

(2) Fit the locating bearing into the lower plummer block<br />

housing, together with the seal and stabilizing ring.<br />

(See Fig. 9.23.)<br />

Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

(5) If the bearing is lubricated with grease, fill the<br />

bearing interior with grease, and apply grease to the<br />

mating surfaces of the upper and lower plummer<br />

block housings. Also, amply apply grease to the<br />

sliding surface of the seal. In the case of a selfaligning<br />

roller bearing, incline the outer ring to allow<br />

a sufficient volume of grease to be packed into the<br />

gaps between the rollers and the cage. (For the<br />

volume of grease, refer to Section 11.)<br />

(6) In the case of oil-lubricated bearings, fill the oil up to the<br />

center of the lowest rolling element. (See Fig. 9.25.)<br />

Fig. 9.27<br />

9.5 Running inspection<br />

Once the bearing arrangement has been assembled,<br />

make sure the assembly work has been correctly<br />

achieved by following the procedure below.<br />

(1) First, turn the bearing by hand to check that the<br />

bearing and seal are free from any irregularities.<br />

a. Non-smooth touch: Trapped dust or scratch<br />

b. Irregular torque: Abnormal interference<br />

c. Excessively large running torque:<br />

Too small bearing clearance, poor flatness of<br />

mounting seat<br />

Fig. 9.25<br />

(7) After filling with lubricant, check the mating surfaces<br />

between the upper and lower plummer block<br />

housings are stably in contact with each other.<br />

Remember to apply grease to the mating surfaces<br />

on the plummer block housings to ensure reliable<br />

sealing and rust-proofing. Then, fully tighten the<br />

tightening bolt. (See Fig. 9.26.)<br />

Note that either the upper or lower housing of a<br />

particular plummer block is incompatible with the<br />

lower or upper housing of another plummer block.<br />

Do not confuse the like housings.<br />

Knock pin seats (Fig. 9.27) are provided at the<br />

corners of the bed so locking knock pins can be driven<br />

into these seats. Use these seats when intending to<br />

install a plummer block with utmost precision.<br />

(2) Next, run the bearing by power. Begin with no load<br />

and at lower speed.<br />

a. Abnormal noise:<br />

Dust, dent mark, or poor lubrication<br />

b. Vibration:<br />

Greater misalignment, or excessively large<br />

residual clearance<br />

(3) Run the bearing under normal operating conditions<br />

to check for temperature rise on the bearing. The<br />

possible causes to abnormal temperature rise with<br />

bearings are as follows:<br />

a. Allowable speed has been exceeded.<br />

b. Overloading<br />

c. Too small residual clearance<br />

d. Negative clearance owing to excessive expansion<br />

or compression with the shaft<br />

e. Warped plummer block owing to poor flatness<br />

with the mounting seat<br />

f. Poor lubrication (excessive or insufficient<br />

lubricant, inappropriate lubrication method of<br />

lubricant)<br />

g. Too great tightening allowance for the contact<br />

seal, or interference with rotating components<br />

such as those around the labyrinth seal<br />

If any irregularity is found as a result of running<br />

inspection, determine and remove the cause. Then,<br />

reperform the running inspection to make sure the<br />

bearing runs normally.<br />

Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

9.6 Maintenance and inspection<br />

To be able to use a bearing to its design life and avoid<br />

any accident, check the following points at regular<br />

intervals.<br />

(1) Running sound on bearing<br />

(2) Temperature on bearing or plummer block<br />

(3) Vibration on shaft<br />

(4) Leaking grease or worn oil seal<br />

(5) Loose tightening and mounting bolts<br />

(6) Trouble-free operation of the lubrication system, and<br />

loosening or leakage with piping<br />

9.7.2 Cylindrical bore bearing<br />

Usually, a cylindrical bore bearing is interference-fitted.<br />

Thus, the bearing is simply drawn out by placing a jig to<br />

the face of the inner ring and exerting a force as<br />

illustrated in Fig. 9.29 with a hand press. However, be<br />

careful not to apply a force to the outer ring. A puller such<br />

as that shown in Fig. 9.30 is often used. When using this<br />

tool, make sure that the jig is fully engaged with the face<br />

of the inner ring.<br />

If the bearing arrangement must be inspected while it is<br />

at a standstill, check it for the following points:<br />

(1) Check appearance the of bearing for any<br />

irregularity.<br />

(2) Fouling of grease, or contaminants (dust or steel<br />

dust) in grease<br />

(3) Loose adapter sleeve<br />

(4) Worn or damaged seal<br />

9.7 Bearing disassembly<br />

9.7.1 Bearing with adapter<br />

Straighten the bent tab on the washer, and loosen the<br />

nut by two to three turns. Place a drift to a face of the nut.<br />

Lightly tap the drift to turn the sleeve (Fig. 9.28). Once<br />

the sleeve is shifted in the axial direction, the bearing can<br />

be easily removed.<br />

Note, however, when the nut has been excessively<br />

loosened and only a few ridges remain engaged, and if<br />

the nut is further tapped, the threading on the sleeve or<br />

nut may be stripped.<br />

Handling the <strong>Plummer</strong> <strong>Blocks</strong> and Bearings<br />

9.8 Cleaning the bearing<br />

Clean the removed bearing with diesel oil or kerosene.<br />

Use two vessels: one for rough cleaning and the other for<br />

finish cleaning. Prepare a cleaning station that has a<br />

metal screen as illustrated in Fig. 9.31 so that the bearing<br />

does not directly contact the fouling on the bottom of<br />

vessel. In rough cleaning, virtually all oil and foreign<br />

matters should be removed from the bearing which<br />

should be immediately transferred to the finish vessel.<br />

The finish vessel must be provided with a filter unit to<br />

maintain the cleaning agent clean.<br />

Once cleaned, the bearing must be immediately rustproofed.<br />

The bearings (which have been carefully removed) must<br />

be checked whether they can be reused. The judging<br />

criterion for reuse should be determined considering the<br />

following criteria through a trial-and-error basis.<br />

(1) Scheduled operating duration to next regular<br />

inspection<br />

(2) Importance of the machine that uses the bearing in<br />

question<br />

(3) Operating conditions such as loading and bearing<br />

speed<br />

(4) Severity of damage on the rolling contact surface<br />

(5) Tendency of increasing bearing clearance and wear<br />

on the cage<br />

(6) Loss in accuracy, etc.<br />

9.9 Storing the bearing<br />

When storing a bearing, pay particular attention to rust<br />

prevention. Note that the rust-proofing grease in the<br />

bearing will run away at a temperature of 50 to 60˚C.<br />

Therefore, store a bearing in a dry, cool location at a<br />

height at least 30 cm above the floor. Remember that<br />

wooden crate attracts moisture. Thus, immediately<br />

unpack the delivered bearings, and store them on<br />

shelves.<br />
