SERIES M 

Gear unit selection is made by comparing actual loads with catalogue ratings. Catalogue ratings are based on a standard set 

of loading conditions, whereas actual load conditions vary according to type of application. Service Factors are therefore used 

to calculate an equivalent load to compare with catalogue ratings. 

i.e. Equivalent Load = Actual Load x Service Factor 

Mechanical ratings and service factors Fm and Fs 

Mechanical ratings measure capacity in terms of life and/or strength, assuming 10 hr/day continuous running under 

uniform load conditions. 

Catalogue ratings allow 100% overload at starting, braking or momentarily during operation up to 10 hours per day. 

The unit selected must therefore have a catalogue rating at least equal to half maximum overload. 

Mechanical Service Factor Fm (Table 1) is used to modify the actual load according to daily operating time, and type of 

loading. 

Load characteristics for a wide range of applications are detailed in Table 3 opposite, which are used in deciding the 

appropriate Service Factor Fm from Table 1. 

If overloads can be calculated, or accurately assessed, actual loads should be used instead of Fm. 

For units subjected to frequent stop/starts overloads in excess of 10 times/day multiply factor Fm x Factor Fs (table 2). 

For applications where units are to operate in extremely dusty or moist/humid atmospheres unit selection should be referred to 

our application engineers.

Motorized backstop modules can be fitted between the gear unit and motor. The backstop device incorporates high quality centrifugal lift 

off sprags which are wear free above the lift off speed (n min). 

To ensure correct operation motor speed must exceed lift off speed. 

Suitable for ambient temperature -220 o F to + 122 o F

Maximum permissible overhung loads 

When a sprocket, gear etc. is mounted on the shaft a calculation, as below, must be made to determine the overhung load on the shaft, and the 

results compared to the maximum permissible overhung loads tabulated. Overhung loads can be reduced by increasing the diameter of the 

sprocket, gear, etc. If the maximum permissible overhung load is exceeded, the sprocket, gear, etc. should be mounted on a separate shaft, 

flexibly coupled and supported in its own bearings, or the gear unit shaft should be extended to run in an outboard bearing. Alternatively, a larger 

gear is often a less expensive solution. 

Permissible overhung loads vary according to the direction of rotation. The values tabulated are for the most unfavourable direction with the unit 

transmitting full rated power and the load P applied midway along the shaft extension. Hence they can sometimes be increased for a more 

favourable direction of rotation, or if the power transmitted is less than the rated capacity of the gear unit, or if the load is applied nearer to the gear 

unit case. Refer to Application Engineering for further details. In any event, the sprocket, gear etc. should be positioned as close as possible to 

the gear unit case in order to reduce bearing loads and shaft stresses, and to prolong life. 

All units will accept 100% momentary overload on stated capacities.

THERMAL POWER RATING 

Thermal Ratings (HP) 

Thermal ratings are a measure of the units ability to dissipate heat, if they are exceeded the lubricant may break down 

resulting in premature gear failure. 

Thermal ratings are based on an ambient temperature of 68ºF, when units are to operate at other ambient temperatures the 

thermal HP ratings must be multiplied by the following factors

Product Safety Information 

IMPORTANT 

General - The following information is important in ensuring safety. It must be brought to the attention of personnel involved in the selection of 

the equipment, those responsible for the design of the machinery in which it is to be incorporated and those involved in its installation, use and 

maintenance. 

The equipment will operate safely provided it is selected, installed, used and maintained properly. As with any power transmission equipment 

proper precautions must be taken as indicated in the following paragraphs, to ensure safety. 

Potential Hazards - these are not necessarily listed in any order of severity as the degree of danger varies in individual circumstances. It is 

important therefore that the list is studied in its entirety:- 

1) Fire/Explosion 

(a) Oil mists and vapour are generated within gear units. It is therefore dangerous to use naked lights in the proximity of gearbox openings, 

due to the risk of fire or explosion. 

(b) In the event of fire or serious overheating (over 300 o C), certain materials (rubber, plastics, etc.) may decompose and produce fumes. 

Care should be taken to avoid exposure to the fumes, and the remains of burned or overheated plastic/rubber materials should be handled 

with rubber gloves. 

2) Guards - Rotating shafts and couplings must be guarded to eliminate the possibility of physical contact or entanglement of clothing. It should 

be of rigid construction and firmly secured. 

3) Noise - High speed gearboxes and gearbox driven machinery may produce noise levels which are damaging to the hearing with prolonged 

exposure. Ear defenders should be provided for personnel in these circumstances. Reference should be made to the Department of 

Employment Code of Practice for reducing exposure of employed persons to noise. 

4) Lifting - Where provided (on larger units) only the lifting points or eyebolts must be used for lifting operations (see maintenance manual or 

general arrangement drawing for lifting point positions). Failure to use the lifting points provided may result in personal injury and/or damage 

to the product or surrounding equipment. Keep clear of raised equipment. 

5) Lubricants and Lubrication 

(a) Prolonged contact with lubricants can be detrimental to the skin. The manufacturer's instruction must be followed when handling 

lubricants. 

(b) The lubrication status of the equipment must be checked before commissioning. Read and carry out all instructions on the lubricant plate 

and in the installation and maintenance literature. Heed all warning tags. Failure to do so could result in mechanical damage and in 

extreme cases risk of injury to personnel. 

6) Electrical Equipment - Observe hazard warnings on electrical equipment and isolate power before working on the gearbox or associated 

equipment, in order to prevent the machinery being started. 

7) Installation, Maintenance and Storage 

(a) In the event that equipment is to be held in storage, for a period exceeding 6 months, prior to installation or commissioning, application 

engineering must be consulted regarding special preservation requirements. Unless otherwise agreed, equipment must be stored in a 

building protected from extremes of temperature and humidity to prevent deterioration. 

The rotating components (gears and shafts) must be turned a few revolutions once a month (to prevent bearings brinelling). 

(b) External gearbox components may be supplied with preservative materials applied, in the form of a "waxed" tape overwrap or wax film 

preservative. Gloves should be worn when removing these materials. The former can be removed manually, the latter using white spirit as 

a solvent. 

Preservatives applied to the internal parts of the gear units do not require removal prior to operation. 

(c) Installation must be performed in accordance with the manufacturer's instructions and be undertaken by suitably qualified personnel. 

(d) Before working on a gearbox or associated equipment, ensure that the load has been removed from the system to eliminate the 

possibility of any movement of the machinery and isolate power supply. Where necessary, provide mechanical means to ensure the 

machinery cannot move or rotate. Ensure removal of such devices after work is complete. 

(e) Ensure the proper maintenance of gearboxes in operation. Use only the correct tools and approved spare parts for repair and 

maintenance. Consult the Maintenance Manual before dismantling or performing maintenance work. 

8) Hot Surfaces and Lubricants 

(a) During operation, gear units may become sufficiently hot to cause skin burns. Care must be taken to avoid accidental contact. 

(b) After extended running the lubricant in gear units and lubrication systems may reach temperatures sufficient to cause burns. Allow 

equipment to cool before servicing or performing adjustments. 

9) Selection and Design 

(a) Where gear units provide a backstop facility, ensure that back-up systems are provided if failure of the backstop device would endanger 

personnel or result in damage. 

(b) The driving and driven equipment must be correctly selected to ensure that the complete machinery installation will perform satisfactorily, 

avoiding system critical speeds, system torsional vibration, etc. 

(c) The equipment must not be operated in an environment or at speeds, powers, torques or with external loads beyond those for which it was 

designed. 

(d) As improvements in design are being made continually the contents of this catalogue are not to be regarded as binding in detail, and 

drawings and capacities are subject to alterations without notice. 

The above guidance is based on the current state of knowledge and our best assessment of the potential hazards in the operation of 

the gear units. 

Any further information or clarification required may be obtained by contacting an Application Engineer.
