Poor lubrication bearing
Anti-friction bearings must be lubricated to prevent metal-to-metal contact between the rolling elements, raceways and retainers. In addition, lubrication protects the bearing against corrosion and wear, helps dissipate heat, helps seal out solid and liquid contamination, and reduces bearing noise.
