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.

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