Bearing Washers | McMaster-Carr

Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds.

Ultra-Low-Friction Oil-Embedded Thrust Bearings

For applications with frequent starts and stops, the oil in these bearings contains particles of slippery PTFE that lubricate the bearing during startup.

High-Load Food Industry
Oil-Embedded Thrust Bearings

Made of 863 bearing bronze and embedded with NSF registered H1 oil, these bearings can tackle high-load applications in food plants, such as bottling and filling lines.

Food Industry Oil-Embedded Thrust Bearings

The oil in these bearings is suitable for incidental contact with food.

High-Load Ultra-Low-Friction
Oil-Embedded Thrust Bearings

Use these bearings for frequent starts and stops in high-load applications. For low friction coefficients, they release a thin layer of an embedded PTFE lubricant during startup friction.

Dry-Running Thrust Bearings

Light Duty Dry-Running Thrust Bearings

Use where high loads and speeds are not required.

Ultra-Low-Friction Dry-Running Thrust Bearings

Use these bearings in applications with frequent starts and stops because they operate with very little friction.

High-Temperature Dry-Running Thrust Bearings

Graphite provides a layer of dry lubrication that operates in high-temperature environments.

Water-Resistant Dry-Running Thrust Bearings

Good for underwater applications, these bearings won’t swell or warp when wet.

Food Industry Dry-Running Thrust Bearings

Made of FDA listed materials for use in food applications, these bearings also withstand caustic and washdown environments.

High-Load Dry-Running Thrust Bearings

A metal backing adds strength.

Chemical-Resistant Dry-Running Thrust Bearings

These bearings stand up to a wider range of chemicals than other dry-running thrust bearings.

Thrust Bearings

Multipurpose Thrust Bearings

These leaded bronze bearings are strong, wear resistant, and excellent at handling shock loads.

Corrosion-Resistant Thrust Bearings

The addition of iron and aluminum gives these aluminum-bronze bearings high strength and excellent corrosion resistance—making them suitable for use in marine and mining applications.

Round Shims

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.

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.

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.

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.

Color-Coded Ring Shims

Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims, which are color-coded by thickness for easy identification.

Color-Coded Ring Shim Sets

Be prepared with ring shims in a variety of thicknesses. These shims are color-coded by thickness for easy identification.

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.

Wave Disc Springs

Use these high-carbon steel springs in noncorrosive environments.

Corrosion-Resistant Wave Disc Springs

Made of stainless steel, these springs are more corrosion resistant than steel wave disc springs.

Split Wave Disc Springs

A gap allows these springs to compress without widening, so they won't bind or deform when used inside a housing with tight clearance.

Stacked Wave Disc Springs

Multiple rows of waves allow these springs to handle higher loads than standard wave disc springs.

Corrosion-Resistant Stacked Wave Disc Springs

Made of 17-7 PH stainless steel with multiple rows of waves, these springs are more corrosion resistant than steel springs and handle greater loads than standard wave disc springs.

Belleville Disc Springs

Belleville Disc Springs for Ball Bearings

Install these springs, also known as bearing preload washers, against ball bearings to reduce noise and unwanted movement along the shaft.

Belleville Disc Springs

Use these steel springs in noncorrosive environments.

Corrosion-Resistant Belleville Disc Springs

Made of stainless steel, these springs are more corrosion resistant than steel springs. Use them on shafts, bolts, and the ends of valves to maintain tension and separate components.

Extreme-Temperature Belleville Disc Springs

These springs withstand temperatures from -400° to 1100° F. All are 718 nickel, a high-strength, corrosion-resistant alloy that's also known as Inconel.

Belleville Disc Springs for Flange Bolts

Keep pipe flange connections sealed during demanding applications. When installed under flange bolt heads, these springs compensate for shock loads, vibration, and thermal expansion and contraction.

Mil. Spec. Belleville Disc Springs

These springs meet MIL-W-12133.

Finger Disc Springs

Raised tabs, known as fingers, enable these springs to compress without widening, so they won't bind or deform in housings with little clearance. Use with ball bearings in precision and high-speed drive assemblies to reduce noise, vibration, and wear.

Shaft Grommets

Support shafts, bearings, and other moving parts that are routed through a hole. These grommets are slippery to allow parts to move freely in the hole. Install them on thin sheet-metal panels.
