These bearings are only available on a made-to-order basis. KMS offers the unique "XR" Series bearing style with deep groove, 4-point contact ball groove geometry. This design enables the bearing to handle simultaneous radial, axial and moment loading while maintaining stiffness. As a bonus, they also have minimal radial and axial play. The "XR" groove design will not lock up in the presence of off center loads. These are made to order and minimum quantities may apply.
