All ceramic bearings have the characteristics of anti magnetic and electrical insulation, wear resistance, corrosion resistance, oil-free self-lubricating, high temperature and high cold resistance, and can be used in extremely harsh environments and special working conditions. The collar and rolling elements are made of zirconia (ZrO2) ceramic material, and the retainer uses polytetrafluoroethylene (PTFE) as the standard configuration. Generally, glass fiber reinforced nylon can also be used

66 (RPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu), etc. A unidirectional thrust ball bearing is composed of a washer shaped ring with a ball rolling raceway and a cage assembled with the ball. Can withstand axial loads, but cannot withstand radial loads
