Among these 3 material HDPE, PP and UPE, UPE have more excellent strength and low friction and could be used to lower temperature (lowest to -150℃).UPE plastic bearings could be used for long-time working temperature on 110C, The ball indentation hardness is 170HRC, the tensile stress is 70.

HDPE,PP,UPE(UHMWPE) are approved can be used in faintish acid and alkali environment (30% CuCl2 solution and 30% NAOH solution is tested ok). Generally the rings and cage were made with HDP PP or UPE, balls were made with glass stainless or ceramic.

Such bearings can be operated in liquid and contamination sensitive environments as acid/alkali/salt/solvent/oil/gas/seawater, and have general performance of lubrication and maintenance free, none magnetism, anti-rust and eroded of plastic bearings. But UPE plastic bearings have not strong mechanical strength, and easy to be out of shape, so couldn't be used in heavy load and high-speed application.
