Cases

Bearing retainer refers to a bearing part that partially wraps all or part of the rolling body and moves with it to isolate the rolling body, and usually guides the rolling body and keeps it in the bearing.

Bearing copper retainer has good friction reduction and wear resistance. Copper alloy has the characteristics of good thermal conductivity, small friction coefficient, good formability and high service temperature.

Bearing copper retainer has stamping and solid two kinds, stamping is only suitable for small and medium-sized. Brass plate, brass castings or brass forgings brass has high tensile strength, mechanical strength and steel plate stamping cage, but the density is relatively small, high limit speed. Not affected by lubricants, including synthetic oils and lipids; Brass cages should not be used above 300°C or in ammonia (e.g. cooling), where ammonia causes seasonal cracking of brass and operating temperatures below 300°C.
