Category Details

A selection of Roller One Way Bearings. Roller Clutch Bearings rotate in one direction only.

  • One way bearings, also known as clutch bearings, or non-reversing bearings, allow rotation in a single direction.
  • Commonly used in over-runnung, or backstopping applications.
  • The unidirectional operation allows these bearings to play a crucial role in various mechanical systems where controlled rotation, overrunning protection, backstopping, indexing, or intermittent motion is required.
  • Recommended Shaft Diameter for Clutch Bearings without Inner Ring is +0.000 / -0.005 mm.
