List Price: $24.80
OR

This bearing application features the KMS "XR" series bearing construction that is 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 a Mobile Satellite dish 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

Customizable Design: Custom designs are readily and inexpensively made from plastics. 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.
