UKF Spindle Bearings with Spacer Ball (rolling ball guidance)

Angular Contact Ball Bearings

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

like 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).

  • Contact angle 16ยบ, form factor to DIN 628 Part 5
  • Precision P5…P4…P2…HQ
  • double row with rolling ball guidance (Spacer Balls)
    • Type series K (manufacturer’s standard) and UK (dimensional series 20)
    • Type series UL (like Bearings of Series 72) and UM (like Bearings of Series 73)
