Ring Shims

Precisely align, level, and adjust spacing on fasteners and shafts with these shims.

Ring Shim Sets

Be prepared with ring shims in a variety of thicknesses. These shims fit around fasteners and shafts to precisely align, level, and adjust spacing.

Wide-Rim Ring Shims

Also known as machinery bushings, these shims have an oversized OD to create a larger bearing surface for reduced wear between moving parts.

Tight-Fit Ring Shims

For a snug fit around a shaft, the ID of these shims is held to a tighter tolerance than other round shims.

Peel-Away Layered Ring Shims

These shims are made of layers of metal bonded with adhesive. Remove layers with a utility knife until you get the thickness you need.

Shims for Ball Bearings

Adjust spacing between bearings and other components on shafts. These shims are sized to fit the outer rim of a bearing.

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.

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.

Unthreaded Spacers for Keyed Shafts

Also known as arbor spacers, these are notched to space components on a keyed shaft.

Ring Shim Assortments

Use round shims to precisely align, level, and adjust spacing on shafts and machinery.
