Assembling input and output elements
NOTICE
Damage to bearing, housing or shafts due to incorrect mounting.
Possible damage to property.
• Only use a mounting device for installing input and output elements (see below).
Use the threaded centering bore at the shaft end.
• Never force belt pulleys, couplings, pinions, etc. onto the shaft end by hitting
them with a hammer.
• When installing the belt pulleys, make sure the belt is tensioned correctly in ac-
cordance with the manufacturer's instructions.
• Make sure the transmission elements are balanced after fitting and do not give
rise to any impermissible radial or axial forces.
INFORMATION
Mounting is easier if you first apply lubricant to the output element or heat it up briefly
to 80 – 100 °C.
Using a mounting device
The following figure shows a mounting device for installing couplings or hubs on gear
unit or motor shaft ends. Should you be able to tighten the screw without any prob-
lems, you may not need the thrust bearing on the mounting device.
