Bearing.Plastic Bearing PEEK Plastic Bearing
PEEK is a plastic with the highest thermal and chemical resistance among moldable crystalline resins.
It has good machinability, mechanical strength, and wear resistance, and can work at a high temperature (250 °C ).
It also has high resistance to radiation, so it is slightly deformed when it is exposed.
