About Thrust Ball Bearings

  • Thrust bearings are designed primarily to support axial loads at contact angles between 30° and 90°.
  • Similar to radial bearings, thrust bearing designs may incorporate balls or rollers as rolling elements.
  • With thrust bearings, it is necessary to supply an axial preload in order to prevent slipping between the bearing's rolling elements and raceways.
