Needle bearing cage and ring material selection

 cage materials
(A) the vast majority of Tapered bearing steel cages are used, the most widely used low-carbon steel stamping ribbon, basket-shaped, box-shaped, etc. cage, suitable for high-carbon chromium bearing steel bearing operating conditions and the environment; carbon steel plate stamping with a cage for bearing steel with a corrosion-resistant bearings working conditions and the environment.
(2) smooth surface with good quality non-ferrous metals. Work under high temperature conditions, can be silicon bronze manufacturing entities maintain operating temperatures up to 315 degrees Celsius; Because aluminum lower intensity than brass, light weight, and thus commonly used aluminum and brass solid cage, mainly used in high speed , lighter weight, corrosion resistance and other working conditions.
(3) using engineering plastics cage, another great development in recent years, mainly because it has a certain degree of corrosion resistance, self-lubricating properties, friction is small, easily obtained, cheap, easy to manufacture, etc., but Easy "aging." Currently used most widely reinforced nylon 66, it can continue to work in the temperature range of -40 to 120 degrees Celsius.
PTFE high strength, self-lubricating properties, continuous working temperature up to 300 degrees Celsius, phenolic tape has high mechanical strength, good wear resistant properties, but expensive for high-speed spin around, working temperature -40 to 150 degrees Celsius, the instantaneous up to 180 degrees Celsius.development of stainless steel bearing; for simplifying a process, should be developed and short high-frequency quenching carburizing bearing steel, bearing steel; in order to meet the needs of the aerospace, high temperature bearing steel should be developed.
