Bearings for Underwater Applications


KMS bearings made from engineered polymers and 316 stainless steel can run in and around water without the worry of corrosion or lubrication.  KMS polymer materials have low water absorption and offer good wear properties for long life. KMS polymer races are more forgiving than metal and allow particles to flow in and thru the bearing. KMS bearings made from food and medical grade 316 stainless have higher corrosion resistance than conventional steel or 440c stainless bearings thereby preventing rust and bearing lock up.

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.
