Ball Screw Support/Thrust Bearings

Ball screw support bearings are specially designed for higher axial loading, accuracy and increased thrust loads that are typical with ball screw support applications. The typical ball screw support bearings are angular contact bearings in duplex, triplex and quadruplex configuration. Other ball screw support designs consist of an assembly with separate thrust and radial roller bearings. Most ball screw support bearings are available in both metric and inch series.

When specifying a ball screw support bearing, the following criteria should be reviewed so the right product is fit to the application.


  • Load rating of the bearing
  • Operating speed
  • Size requirements
