Prevent Bearing Misalignment

20/8/2014· Prevent Bearing Misalignment. Properly aligned bearings can be critical to the life and health of pumps . Misalignment is a frequent cause of rolling bearing failure. It can cause cage fracture, which will result in seizure of the bearing, pump failure and costly downtime. It can also cause edge loading, which will result in early bearing failure.

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.
