Effect of radial force F
on the service life of bearings
q
By selecting a suitable direction of radial force F
on the bearings, caused by the internal rotary group forces
can be reduced, thus optimizing the service life of the
bearings. Recommended position of mating gear is depen‑
dent on direction of rotation. Examples:

10 to 180 ±70 °
Note
▶ The permissible axial force in direction −F
avoided as the lifetime of the bearing is reduced.
▶ Special requirements apply in the case of belt drives.
