Thrust Ball Bearing - 51200 Series

  • 51200 Series.

About Thrust Ball Bearing

  • Thrust ball bearings are divided into single and double direction types.
  • The former is able to accommodate axial load in one direction, while the latter is able to accommodate it in both directions.
  • Neither is suitable for applications that involve radial load or high-speed rotation.
  • Bearings whose housing race back face is spherical (with a spherical back face or aligning seat race) are designed with a self-aligning capability and can accommodate the effects of
    inaccurate mounting.

Features of Ball Thrust Bearing

  • Consists of a row of balls running between two grooved washer rings.
  • The smaller bore ring is referred to as the shaft washer while the larger bore ring is called the housing washer.
  • The ring faces are always mounted parallel to the shaft centerline.
  • The housing washer is made with either a flat or spherical back face.
  • Thrust bearings with spherical faces and washers are self-aligning to compensate for mounting errors.
  • Cages can be pressed steel, copper alloy, and a synthetic resin molded or machined resin cage

Main Applications

  • Automobile steering pivots and machine tool spindles.
