5.3.3
Axial force stressing
When using, for example, helical toothed wheels as drive element, in addition to the radial
force, there is also an axial force on the bearings of the S120M. For axial forces, the spring-
loading of the bearings can be overcome so that the rotor is displaced corresponding to the
axial bearing play present.

approx. 0.35 mm
An axial force as large as the spring-loading is not permitted (100 ... 500 N). Premature failure
is the result when the bearing is not pre-tensioned.
Calculating the permissible axial force: F

NOTICE
Damage due to axial forces on the S120M with holding brake
On an S120M with integrated permanent-magnet-excited holding brake, axial forces at the
shaft extension can cause damage. This applies when installing the system and during
operation.
● Lock the components connected to the shaft in place.
