Ring Shims
Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment.
Stainless steel shims are more corrosion resistant than steel shims. 316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
PTFE plastic shims are slippery, so they can be used to reduce friction between parts. They also have excellent chemical resistance.

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. Use them to precisely align, level, and adjust spacing on shafts and machinery.
Carbon steel shims have excellent strength and can be welded.

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.

Shim Stock
Cut it into custom shapes to fit your application. Sheets come flat packed.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment. Metal shims include a material certificate with traceable lot number. Most shims include a test report.
PTFE plastic shim stock is slippery, so it can be used to reduce friction between parts. It also has excellent chemical resistance.

Electrical-Insulating Sleeve Washers
Also known as shoulder or insulator washers, these nonmetal washers block electrical current and prevent galvanic corrosion from mating different types of metal.
Nylon 6/6 washers have good abrasion resistance. Exposure to moisture may cause them to expand.
PTFE washers have excellent chemical resistance and a slippery surface that resists wear in high-friction applications.
Hard fiber washers resist organic solvents and petroleum-based oil.
