About Plain Bearings

PTFE Unthreaded Spacers

PTFE spacers have a slippery surface and surpass most plastic spacers when it comes to chemical resistance and performance in extreme temperatures.

Chemical-Resistant Plastic Washers

These washers surpass most other plastic washers when it comes to withstanding chemicals, oil, and grease.

Metric Chemical-Resistant Plastic Washers

These metric washers surpass most other plastic washers when it comes to withstanding chemicals, oil, and grease.

Mil. Spec. Chemical-Resistant Plastic Washers

Choose these washers for their adherence to strict military standards for material and construction.

Electrical-Insulating Sleeve Washers

Also known as shoulder washers.

Abrasion-Resistant Rubber
and Plastic Sealing Washers

Made of durable material, these washers resist wear from rubbing and scraping surfaces.

Ring Shims

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

Shim Stock

Cut this stock into custom shapes to fit your application.

Dry-Running Sleeve Bearings

High-Load Dry-Running Sleeve Bearings

A metal shell adds strength.

Food Industry Dry-Running Sleeve Bearings

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

Ultra-Low-Friction Dry-Running Sleeve Bearings

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

Chemical-Resistant Dry-Running Sleeve Bearings

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

Water-Resistant Dry-Running Sleeve Bearings

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

Multipurpose Dry-Running Sleeve Bearings

Reinforced with polyester fabric, these plastic bearings have load and speed capabilities comparable to metal bearings.

Dry-Running Flanged Sleeve Bearings

Food Industry Dry-Running Flanged Sleeve Bearings

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

Ultra-Low-Friction Dry-Running
Flanged Sleeve Bearings

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

High-Load Dry-Running Flanged Sleeve Bearings

An aluminum shell adds strength.

Multipurpose Dry-Running Flanged Sleeve Bearings

Reinforced with polyester fabric, these plastic bearings have load and speed capabilities comparable to metal bearings.

Water-Resistant Dry-Running Flanged Sleeve Bearings

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

Dry-Running Thrust Bearings

Food Industry Dry-Running Thrust Bearings

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

Ultra-Low-Friction Dry-Running Thrust Bearings

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

Water-Resistant Dry-Running Thrust Bearings

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

High-Load Dry-Running Thrust Bearings

A metal backing adds strength.

Linear Bearings

Linear Sleeve Bearings

Because they usually do not require lubrication, linear sleeve bearings outperform linear ball bearings in dirty environments.

Ultra-Thin Linear Sleeve Bearings

Thinner than standard linear sleeve bearings, these bearings fit where clearance is a concern.

Dust-Resistant Linear Sleeve Bearings

Ridges on the inside of these bearings wipe away dust and debris as the bearing travels on a shaft.

Food Industry Linear Sleeve Bearings

Made of FDA-listed materials for use in food applications, these bearings also have excellent chemical and corrosion resistance.

Electrical-Insulating Linear Sleeve Bearings

These fiberglass bearings are lightweight, nonmagnetic, and won’t conduct electricity.

Linear Sleeve Bearings for Support Rail Shafts

Sleeve bearings outperform ball bearings in dirty environments. Use them for low speed applications.

Food Industry Linear Sleeve
Bearings for Support Rail Shafts

Made of FDA-listed materials for use in food applications, these bearings also have excellent chemical and corrosion resistance.
