Request Information
SR bearings are made to a standard setting range, based on Timken’s Set-Right™ automated setting technique, and are suitable for most industrial applications. They have two spacers and an optional snap-ring for axial location. Because both types are made from popular sizes of single-row bearings, they provide a low-cost choice for many applications.

Design Attributes:
  • Two TS bearings mounted indirectly with cone and cup spacers.
  • Cup spacer features lubrication slots to allow commercial snap rings to locate bearings axially.
  • Two J-Line™ Class N bearings with metric envelop and non-metric internal geometry.
