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).

Bearing Misalignment

• 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.
