Needle bearing cage and ring material selection

Cage material
(A) the vast majority of 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 Stainless steel slewing 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 manufactured silicon bronze solid cage, operating temperature up to 315 degrees Celsius; Because aluminum lower intensity than brass, light weight, and thus commonly used aluminum and brass solid cage, mainly applied to speed higher proportion of light, corrosion and other 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.
Rings and rolling material
(A) carbon chromium bearing steel
Most bearing rings and rolling elements are colored with a special steel manufacturing. With high carbon chromium bearing steel (GCr15 and GCr15SiMn with ZGCr15 and ZGCr15SiMn) manufacture rings and rolling elements, their parts hardness as follows:
GCr15 and ZGCr15 materials with ferrule and the roller is HRc61 ~ 65, the ball was HRc62 ~ 66;
With GCr15SiMn and ZGCr15SiMn material of the ferrule and the roller is HRc60 ~ 64, the ball was HRc60 ~ 66.
With high carbon chromium bearing steel bearings are generally applicable to the operating temperature range of -40 to 130 degrees, the oil and greased properly. Can meet the requirements of general machinery.
Carbon chromium bearing steel bearing parts at high temperature back too far, its adaptation to temperature up to 250 degrees.
