TECHNICAL INFORMATION
Benzler worm gears BS 40-71 have a symmetrical
gear-housing manufactured in aluminium. BS 88 and
112 have a gearhousing of cast-iron.
The worm wheel is made of centrifugal cast tinbronze
and the worm screw is case-hardened and ground.
All motor connections are according to IEC-standard
and for BS 40-112 with elastic coupling. This means
the following advantages:
bearings and are not connected with the motor
bearings. This means longer lifetime and a
smoother drive..
40-112.
the gear..
The worm geared motor is available for mounting on
any position.
The gear can be combined with Benzlers’ remaining
range of helical and worm gears to provide very low
output speeds. All data given in this catalogue applies
aluminium and are available in B5 and B14, larger

onto a wall or foundation and bolted through the 4
bolt holes in the gear casing.

The coating is a recently developed surface coating method
for aluminium.
The coating means that the material surface is, by a
chemical process, converted into an aluminium oxide,
which gives a very hard, ceramic, surface finish.
The oxide layer is then impregnated and coated with
connection between oxide and plastic is created.
