Plastic radial ball bearings are used underwater in rotary spa jets to enable the jets to spin freely with minimal water pressure. They operate in a hostile environment with the challenges of hot water, chlorination, suspended dirt, sand, body lotion, hair etc.
Critical Design features: POM, PBT, or PP plastic races and cage fitted with 316 stainless balls. Bearing construction features True Race Technology™ ball grooves and anti-clogging bearing designs.
Additional reasons for use:
Low friction: Spinning water jets need to be able to rotate with standard water pressure to deliver a pulsating water massage.
A KMS bearing is designed to tolerate suspended particles without clogging.
Part integration: A KMS bearing can be designed and manufactured as an integrated assembly that can reduce parts count and assembly time while improving performance.
