High Precision Spindle Bearings with Spacer Ball (rolling ball guidance)

UKF Spindle Bearings with Spacer Ballslike Bearings of Type series 70, 72 and 73 (double row). Long lifetime through high precision bearings. This configuration provides a slight self-aligning preload; consequently, the balls remain under equal preload. These Bearings carry both radial and axial loads and provide spherical contact of the balls (DF).
