HDPE Plastic Bearings , Anti-Acid And Anti-Alkali Plastic Bearings

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).

HDPE plastic bearings could be used for long-time working temperature on 90C, The ball indentation hardness is 50HRC, the tensile stress is 25. 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 HDPE 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.

Generally the rings and cage were made with HDP PP or UPE, balls were made with glass stainless or ceramic.
