Aluminum Cage

High precision roller guide bearings(aluminum cage), made of aluminum as base material, are produced by the process of being distributed quality hardened steel balls with certain angle and density. They are in conformity with the European RoHS environmental protection standards and widely used in the applications of cold punching mold and precision machinery due to the advantages of low friction coefficient, good self-lubricating and stable size.
