    HDPE / PP / UPE 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). 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 these 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. Among these 3 material, UPE have more excellent strength and low friction and could be used to lower temperature (lowest to -150℃). Generally the rings and cage were made with HDP PP or UPE, balls were made with glass stainless or ceramic.
     
    The material of rings and cage: HDP, PP, UPE material.
    The material of Balls: Glass Stainless, Ceramic material.
