A REVIEW ON SELECTION OF MATERIALS USED FOR BALL BEARING

The bearing industry uses different materials for the production of the various bearing components. The materials are processed to achieve desirable properties to maximize bearing performance and life. The materials described here are the most commonly used. This paper highlights the various materials used for ball bearing. Temperature rise is the limiting factor to increase rotating speed. Ball bearings with ceramic balls have been gradually used on many high speed rotating systems due to low material density, low thermal expansion, high young’s modulus and hardness. A review on polymer materials is done which are widely used for cryogenics. Suitable composite materials like silicon nitride and Aluminum oxide are suggested for carrying out the research work
