bearing:Cage assembly generally made of quality carbon steel, and 15CrMo and other quality alloy steel or nylon cage assembly
bearing:Cage assembly generally made of quality carbon steel, and 15CrMo and other quality alloy steel or nylon cage assembly sometimes. Treated in chemical way, the steel cage assembly is of enough intensity and wear resistance property. The maxi working temperature of nylon cage reaches about 120, or 180 in short time. Besides, our company could supply copperized cage assembly, silver plated cage assembly, parkerizing cage assembly or other surface treated cage assemblies.The assembly is produced under international standard. The relieved end needle roller and special needle units are available. It is required to make specific requirements when in order. The dimensional tolerance, geometric accuracy and surface hardness of shaft and cover aperture are all proved up to technical requirements of international standard.The surface hardness of bearing race and depth of hardened layer are 58-64HRC and 0.6-1.0mm individually. Besides, the surface roughness of bearing race: Ra≤0.32μm; while in some high-precision occasions: Ra≤0.20μm
