Bearings are high precision parts. Improper handling will lead to premature bearing failure and machine malfunctions. Care should be taken in the handling of bearings. They should be assembled in a clean working environment to ensure that no contaminants infiltrate the bearing and they should be protected from sharp impacts. What follows is an explanation of proper bearing handling procedures.

Preparations before Mounting
Bearing Mounting Surfaces
Any burrs, cutting chips, rust or dirt should first be removed from the bearing mounting surfaces. Installation can then be simplified if the clean surfaces are lubricated with spindle oil.
Burrs, dirt, and other contaminants that infiltrate the bearing before and during mounting will cause noise and vibration during subsequent operation.
Mounting Equipment
Ensure that all pressing blocks, driving plates, hammers and other mounting devices are clean, free of burrs, and of the correct size.
