Standard Available Sizes For Thin Section Bearings

thin Section Bearings Available Sizes

The KMS Thin Section Plastic Ball Bearing features standard Celcon® acetal (POM) rings, machined radial ball groove construction, and 316 stainless balls. Celcon® Acetal POM (PolyOxy-Methylene) is a superior general purpose engineering polymer that provides excellent properties that bridge the gap between metals and ordinary plastics.

These polymer bearings feature single & double row, caged and full complement bearing construction. Alternative balls can be offered upon request. See Ball Materials.

When acetal plastic is not the right fit, we have alternative materials that may be better suited for your application – please contact KMS Bearings for more information.

CUSTOM IS OUR SPECIALTY

Any of the listed standard sizes below can be modified to better suit your application. We can modify the size, material and add mounting features. Consult KMS for a semi-custom and/or custom bearing solution.

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.
