14.2.11.2 Permissible radial forces
Description
As a result of the bearing arrangement, the 1FL2 is designed for aligned forces. Forces such as
these occur for belt drives, for example.
All radial forces always refer to aligned forces.
NOTICE
Motor damage caused by circulating forces
Circulating for
ces can cause bearing motion, and therefore damage the motor.
• Avoid rotating forces.

ame size. It depends on the force application point and the average speed for a
nominal bearing service life (L10h) of 20000 h.
