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

TOP-16 plastic bearing.pdf
TOP-05 diameter list.pdf

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

PP plastic bearings could be used for long-time working temperature on 100C, The ball indentation hardness is 80HRC, the tensile stress is 30.

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 PP 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.
