Shims for Keyed Shafts

Precisely shaped to fit snugly on keyed shafts, these shims align, level, and space components. Because of their tight fit, they also help components rotate in unison with the shaft.

Shims with a notch need the key inserted. They’re often referred to as arbor spacers.

Stainless steel shims are more corrosion resistant than carbon steel shims. Use them in wet environments where rust is a concern.

Carbon steel shims are stronger than stainless steel shims, but shouldn’t be used in wet environments.

Shim Sets for Keyed Shafts

Be prepared with shims in a variety of thicknesses. Also known as arbor spacers, these shims are notched to fit over keyed shafts. Use them to precisely align, level, and adjust spacing. Shims are made of carbon steel for strength and weldability.
