The bearings with chemical resistance and high endurance at a cost effective price

Features and Application

Materials of inner races and outer races are made with either PEEK or PVDF which have high resistance to chemicals and heat..
The PK/PV bearings can be used for transportation system at chemical process, medical equipment and semiconductor washing and cleaning equipment, etc, which are under high temperature.

In Addition:

PE series bearing that use UHMWPE, ultra high molecular weight polyethylene, have been produced since 1970.
