In addition, the machine elements to be driven must be secured axially via
the frontal centering hole.
Damage to property due to reversing mode!
Shaft damage! In case of intense reversing operation, the seat of the fitting
spring may deflect. Increasing deformations can lead to a break of shaft.
Preferably, use plain output shafts.
3.7 Bearing and shaft load
During operation, radial and axial forces act on the motor shaft and the motor
bearings. The design of the machine and the shaft-side mounting of drive ele‐
ments must be coordinated to ensure that the specified load limits are not ex‐
ceeded.

In the case of adjusted point of application of radial force, calculate the al‐
lowed radial force according to the following formula.
