Thrust Ball Bearing



A thrust ball bearing is composed of bearing balls supported in a ring and can be used in low thrust applications with little axial load. Thrust ball bearings are designed to accommodate axial/ thrust loads in one or two directions. They are available in ISO metric and inch series. Thrust ball bearings consist of two hardened and ground thrust plates with matching ball grooves on one side and a 1-piece brass cage that contains the precision balls. A full complement of hops is used without the cell to increase thrust capacity in some low-speed applications. Thrust Ball Bearings are not suitable for high-speed applications. Sliding movement between balls and raceways can occur at high speeds, resulting in smearing.

  • The separable components of thrust ball bearings are interchangeable. This facilitates mounting and dismounting and maintenance inspections.
  • Thrust Ball Bearings consist of a shaft washer, a housing washer, and a ball and cage assembly.
  • They are designed to accommodate axial loads and locate a shaft axially, in one direction only, and must not be subjected to any radial load.
  • Chromium Steel (GCr15) Shaft and Housing Washer provide high uniform hardness and good wear resistance.
