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.
