Thin Section Plastic Ball Bearings

KMS Engineered Polymer Solution For Today’s Design Challenges

thin section ball bearings A KMS thin section plastic ball bearing assembly is constructed with POM Acetal engineering polymer for the races & cage and is fitted with SS316 balls. Alternative polymers and balls can be offered when the standard materials are not best suited for the application. The rings are either all machined on a CNC or injection molded with machined ball grooves for greater accuracy, performance and life. Range of Sizes

Thin Section Plastic Ball Bearings Options



KMS polymer race thin section ball bearings are less expensive when compared to their steel counterparts. Overall cost reduction can be achieved while providing many solutions to age old problems.

  • Cost Savings

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.
