    TECHNICAL DESCRIPTION AND ADVANTAGES

Kynar® resins have been used in critical contact applications for food, beverage, pharmaceutical and semiconductor industries for over 20 years with such applications as membranes, piping, tubes, valves, vessels, and now BEARINGS. This unique polymer offers an array of properties that makes it an outstanding choice and is now offered in a plastic race bearing assembly for superior corrosion resistance in those industries for longer life. PVDF Kynar® Plastic races and cages are fitted with balls made of either Glass, Torlon, 316 Stainless or Ceramic.

Plastic Vs Steel

Product Integration: A plastic bearing can be mounted into other components or parts such as plastic wheels, pulleys or housings. In certain design concepts, seamless integration can be achieved where the bearing will have the pulley profile as the outer ring, and the shaft or a fixing clip replaces the inner ring . This integration lowers assembly time and also results in utilization of fewer parts, increasing affordability.
