KMS Plastic Radial Ball Bearing

About KMS Plastic Radial Ball Bearing

KMS Bearings, Inc. is the world leading manufacturer of plastic and AISI 316 stainless steel bearings.

Making for an innovative, cost effective way to approach an engineering bearing design problem, the solution may be a plastic or AISI 316 Stainless ball bearing. They can ensure your products run smoother, quieter, more efficiently and with less maintenance than conventional steel bearings. You no longer have size, shape and environment limitations.

Corrosion Resistant Bearings

Plastic bearings are available in standard inch and metric sizes. Plastic race bearings can be made in special sizes and types in small and large quantities. Plastic radial ball bearings offer many advantages over standard steel bearings, they are:

•     Corrosion Resistant
•     Design flexibility
•     Bearing & application integration
•     Non magnetic
•     Hygienic
•     Lubrication free
•     Light weight
•     Low inertia- freer turning / low start up torque

KMS bearings manufacture plastic race ball bearing types in single and double row radial, 3- piece thrust, four point contact, thin section, skate wheel ball bearing, insert ball bearing with plastic mounted blocks in either flange or pillow type. The combinations are almost limitless due to the adaptable technology deployed.
Special Plastic Bearings (At KMS Specials are a Standard)

Thermoplastic bearings are readily and inexpensively made from polymers. This allows engineers complete freedom to design the bearing around the device rather than attempting to design the device around a limited range of standard bearings. Thermoplastic ball bearings can be designed with a pulley, sprocket or a fixing clip to the outer ring. We can mold a hex, spline or the shaft as the inner ring. We can design and build complete integrated bearing assemblies for the ultimate in cost savings. Integrating mating component or mounting features will ease assembly, reduce time, reduce errors and reduce the parts count, thereby lowering your overall cost to manufacture.

KMS is the only manufacturer to produce a full product line of radial ball bearings made from AISI 316 stainless. AISI 316 stainless provides superior corrosion resistance when compared to standard 440C stainless bearings. A KMS stainless bearing can run dry, run in liquids or handle high temperatures when fitted with high temperature polymer cage or be made as a full complement type (no cage). They are available in standard or special sizes, inch or metric.

KMS produces mounted blocks from PBT plastic in (2) two and (4) four bolt flange, and pillow type. Mounted blocks made from PBT plastic will never corrode or rust. When fitted with a KMS plastic or AISI Stainless insert ball bearing they will provide superior corrosion resistance to any mounted unit offered today. Additional detailed information on the above is available within the web site. Please feel free to contact KMS directly by phone with any questions you may have on how a KMS bearing can help you.

Exceptional Corrosion Resistance

The KMS Plastic Radial Ball Bearing provides superior corrosion resistance owing to its high-performance plastic construction. This makes it ideal for applications exposed to harsh chemicals, moisture, or corrosive substances, ensuring long-term reliability and consistent operation even in demanding environments.


Optimized for Clean and Hygienic Applications

Specially designed for use in medical and food processing equipment, this bearing is both RoHS compliant and pre-lubricated with food-safe lubricants. The contact seals help prevent contamination, while the plastic materials support hygienic, easy-to-clean assembly in regulated industries.


No Hassle Maintenance and Low Noise Performance

Thanks to its pre-lubricated and maintenance-free architecture, users benefit from reduced downtime and minimal service requirements. The bearing's low noise signature is particularly advantageous in precision equipment, laboratories, or machinery where quiet operation is essential.
