0.251" ID Bearings | 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 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.

Food Industry Oil-Embedded Sleeve Bearings

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

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-Temperature Dry-Running Sleeve Bearings

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

Oil-Embedded Flanged Sleeve Bearings

Startup friction causes these bearings to release a thin layer of oil on the bearing’s surface. They’re flanged, so they handle loads both parallel and perpendicular to the shaft. They’re also known as Oilite® bearings.

High-Load Oil-Embedded Flanged Sleeve Bearings

Food Industry Oil-Embedded
Flanged Sleeve Bearings

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

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.

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.

Dry-Running Flanged Sleeve Bearings

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.

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.

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.

Mounted Bearings

Dry-Running Mounted Sleeve Bearings

Made from slippery materials, these bearings reduce friction without the oily mess.

Dry-Running Mounted Sleeve
Bearings with Two-Bolt Flange

Embedded lubricant particles increase the load capacity of these bearings while also making them slippery.

Light Duty Dry-Running Mounted
Sleeve Bearings with Two-Bolt Flange

Use these nylon or acetal bearings for light loads. The closed backing blocks out dust and other contaminants.

High-Speed Light Duty Dry-Running Mounted
Sleeve Bearings with Two-Bolt Flange

Made of acetal with a PTFE filling, these light duty bearings handle speeds twice as fast as standard acetal bearings can.

High-Speed Dry-Running Mounted
Sleeve Bearings with Two-Bolt Flange

Handling speeds twice as fast as standard mounted sleeve bearings while limiting wear on your system, these bearings are made of PTFE-filled acetal.

Linear Bearings

Linear Sleeve Bearings

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

Linear Sleeve Bearings for Support Rail Shafts

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

Drill Bushings

Press-Fit Drill Bushings

Secure-Hold Drill Bushings for Plastic

Designed to grip slippery plastic, the knurls on these bushings keep them from spinning while you drill. Their hold is stronger than serrated bushings, so they can withstand more force.

Drill Bushings for Plastic

Serrations line the sides of these bushings to keep them from spinning while you drill. Also known as jig bushings, they’re pressed or molded into plastic tooling to guide drill bits, counterbores, and reamers.
