Inner & Outer Race Shims

Preloading your ball bearing system eliminates the extra clearance between the inner race and outer race of the bearing, allowing for smoother mechanical operation. Excessive or insufficient preload, however, can cause more damage than good.

Inner race and outer race bearing shims come in varying thicknesses to help you achieve the right amount of axial preload for your bearings. When installed correctly, bearings shaft shims help prevent misalignment, reduce noise and vibration, improve system rigidity, and extend bearing life. A versatile design also allows use as shaft spacers to align and adjust the spacing between two components.

Ondrives.US manufactures inner and outer race bearing shaft shims in 303 stainless steel or anodized aluminum.  Our ball bearing race shims have a single piece construction and tight width tolerances for a secure fit. Select from hundreds of standard inch widths and bore diameters to suit nearly any application. Metric or custom bearing shaft shims are also available upon request.
 

The Ondrives.US Advantage: Precision Bearing Shaft Shims

We have a strong reputation for engineering and manufacturing high-quality precision mechanical components.  Our bearing shaft shims have tight tolerances and press snugly against the inner and outer race for effective preloading.  A wide range of thickness options ensures you will find the right configuration needed for shimming out components.
  • Made to precise tolerances
