Bearing Alignment and Bearing Misalignment Information || Dynaroll Ball Bearings

Misalignment during assely 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°. Loing shoulders on mating components must be parallel to bearing raceway faces. Shaft and housing bores must be concentric.
