About Plain Bearings

Oil-Embedded Sleeve Bearings

Also known as Oilite® bearings.

Vibration-Damping Oil-Embedded Sleeve Bearings

With a flexible layer of rubber sandwiched between an oil-embedded bronze bearing and rigid metal shell, these bearings reduce wear and machinery noise.

Food Industry Oil-Embedded Sleeve Bearings

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

Panel-Mount Oil-Embedded Sleeve Bearings

Unlike other sleeve bearings, these do not need to be fully inserted into a housing. Their unique shape creates a permanent, secure hold in thin panels.

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

With extra iron and filled with oil containing slippery PTFE, these bearings support heavy loads that frequently start and stop along shafts. They’re sleeve bearings, so they handle loads parallel to the shaft.

High-Load Food Industry
Oil-Embedded Sleeve Bearings

Embedded with oil that is safe for incidental contact with food, these bearings are suitable for use in high-load applications such as bottling and filling lines in food processing plants. They are also known as Super Oilite® bearings.

High-Load Oil-Embedded Sleeve Bearings

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 Sleeve Bearings

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

Dry-Running Sleeve Bearings

High-Load Dry-Running Sleeve Bearings

A metal shell adds strength.

Light Duty Dry-Running Sleeve Bearings

Use where high loads and speeds are not required.

Multipurpose Dry-Running Sleeve Bearings

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

Panel-Mount Dry-Running Sleeve Bearings

Permanently and securely install these self-clinching bearings into panels, with no need for precision-bored holes or machined mounts.

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.

Harsh Environment Dry-Running Sleeve Bearings

Even in the presence of harsh chemicals and extreme temperatures, these bearings operate under heavy loads and at high speeds.

Water-Resistant Dry-Running Sleeve Bearings

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

Ultra-Low-Friction Dry-Running Sleeve Bearings

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

High-Temperature Dry-Running Sleeve Bearings

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

Chemical-Resistant Dry-Running Sleeve Bearings

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

Sleeve Bearings

Multipurpose Sleeve Bearings

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

Multipurpose Sleeve Bearings with Groove

A figure-8-shaped groove provides a flow path for lubricant, distributing it evenly along the bearing’s surface.

Corrosion-Resistant Sleeve Bearings with Groove

Grooves on the inside of the bearing provide a flow path for lubricant, distributing it evenly along the bearing’s surface.

Corrosion-Resistant Sleeve 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.

Dry-Running Flanged Sleeve Bearings

Light Duty Dry-Running Flanged Sleeve Bearings

Use where high loads and speeds are not required.

Easy-Install Dry-Running Flanged Sleeve Bearings

A slit running along the length of these bearings allows you to quickly slip them into a housing—no tools required.

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.

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.

High-Temperature Dry-Running
Flanged Sleeve Bearings

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

Self-Aligning Dry-Running Flanged Sleeve Bearings

Compensating for minor shaft misalignment and not requiring lubrication, these sleeve bearings swivel to self-align and are dry running. They don’t need a housing and you can install and replace them without any tools because they’re slip fit.

Water-Resistant Dry-Running Flanged Sleeve Bearings

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

Multipurpose Dry-Running Flanged Sleeve Bearings

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

High-Load Dry-Running Flanged Sleeve Bearings

An aluminum shell adds strength.

Chemical-Resistant Dry-Running
Flanged Sleeve Bearings

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

High-Speed Self-Aligning Dry-Running
Flanged Sleeve Bearings

Made of acetal with a PTFE filler, these bearings handle velocities up to twice as high as standard acetal bearings. They swivel to compensate for a small amount of shaft misalignment.

Flanged Sleeve Bearings

Multipurpose Flanged Sleeve Bearings

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

Corrosion-Resistant Flanged Sleeve 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.

Multipurpose Flanged Sleeve Bearings with Certification

Furnished with a traceable lot number and material test report, these leaded bronze bearings are strong, wear resistant, and excellent at handling shock loads.

Oil-Embedded Flanged Sleeve Bearings

Also known as Oilite® bearings.

High-Load Oil-Embedded Flanged Sleeve Bearings

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

Food Industry Oil-Embedded Flanged Sleeve Bearings

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

Ultra-Low-Friction Oil-Embedded
Flanged Sleeve 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 Ultra-Low-Friction
Oil-Embedded Flanged Sleeve Bearings

With oil for reduced friction and iron for added strength, these bearings handle frequent stops and starts in high-load applications.

Oil-Embedded Flanged Sleeve
Bearings with Certification

These bearings come with a traceable lot number and material test report. They are also known as Oilite® bearings.

High-Load Food Industry Oil-Embedded
Flanged Sleeve Bearings

Support heavy loads that are often found in bottling and filling lines in food plants—these bearings contain extra iron and FDA-compliant oil. They’re flanged, so they handle loads both parallel and perpendicular to the shaft.

Wheel Reducer Bushings

Reduce the inside diameter of a bearing to fit a particular axle size. Also known as spanner bushings.

Bushings for Sprockets and Pulleys

Light Duty Sleeve Bushings

Reduce the ID of sprockets, pulleys, and gears in low-torque applications.

Self-Adjusting Spring Bushings

A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit.

Fabricating and Machining

Circular Saw Blade Diamond-to-Round Arbor Adapters

Convert a diamond arbor hole to a round arbor hole.

Circular Saw Blade Arbor Reducer Bushings

Reduce the diameter of a blade's arbor hole to fit your saw's arbor.

Reducer Bushings for Bench
and Pedestal Grinding Wheels

Insert these bushings into the arbor hole of your grinding wheel to attach wheels to smaller diameter shanks.
