    TECHNICAL DESCRIPTION AND ADVANTAGES

This bearing application features the KMS "XR" series bearing construction that contains a deep 4-point contact ball groove geometry. The design enables the bearing to handle simultaneous radial, axial, and moment loading while maintaining stiffness. As a bonus, the bearing is produced with minimal radial and axial play. The "XR" groove design will not lock up in the presence of off center loads. It was originally designed for an outdoor security camera application. This bearing is constructed with Acetal plastic rings and cage and fitted with SS316 balls. This OD is as molded. MADE IN THE U.S.A

Case Study

Plastic Vs Steel

Corrosion Resistant: KMS plastic ball bearings can be utilized in environments destructive to conventional bearings. Plastic, by its nature, does not corrode. Our bearings can operate in hostile environments such as sea water, silicon wafer processing, plating solutions and swimming pools.
