Misalignment during assembly is a common cause of bearing
noise, increased torque, and general poor performance. The free
angle of misalignment that a small bearing can tolerate is typically
less than 1°. (See page 13).

- Locating shoulders on mating components must be parallel to
bearing raceway faces.
- Shaft and housing bores must be concentric. This is
particularly true when more than 2 bearings share a common
component. For example, if a third bearing is added to the above
arrangement, the resulting assembly has almost no tolerance for
misalignment of the bearing outer ring.
