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.
