About Plain Bearings

Oil-Embedded Sleeve Bearings

Also known as 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.

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.

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.

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

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.

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.

Dry-Running Flanged Sleeve Bearings

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.

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.

High-Temperature Dry-Running
Flanged Sleeve Bearings

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

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-Load Dry-Running Flanged Sleeve Bearings

An aluminum shell adds strength.

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-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.

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.

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.

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.

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.

High-Load Food Industry Oil-Embedded
Flanged Sleeve Bearings

Embedded with lubricant that’s FDA compliant for incidental food contact, these bearings are good for high-load applications such as bottling and filling lines in food plants.
