Noise & vibration testing
BEARING INTERNAL CLEARANCE
The main objective of lubrication is to prevent direct metal-to-metal contact between the bearing rings and the rolling elements by means of a lubricant film. In this way,wear and premature rolling fatigue are avoided. Inaddition,lubrication reduces the development of noise and friction, thus improving the operating characteristics of a bearing. Additional functions may include protection against corrosion and heat dissipation form the bearing.
