About Linear Bearings

Linear Sleeve Bearings

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

Dust-Resistant Linear Sleeve Bearings

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

Ultra-Thin Linear Sleeve Bearings

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

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.

Mounted Linear Bearings

Chemical-Resistant Flange-Mounted
Linear Sleeve Bearings

The Frelon liner on these bearings allows them to stand up to a wider range of chemicals than other flange-mounted linear sleeve bearings.

Mounted Linear Sleeve Bearings

Virtually maintenance free, these bearings have slippery, chemical-resistant liners that don't require added lubrication.

High-Load Mounted Linear Sleeve Bearings

With two bearings mounted in one housing, these sleeve bearings can handle heavier loads than standard mounted linear sleeve bearings.

Mounted Linear Sleeve
Bearings for Support Rail Shafts

Virtually maintenance free, these bearings have slippery, chemical-resistant liners that don't require added lubrication.

High-Load Mounted Linear Sleeve
Bearings for Support Rail Shafts

With two bearings mounted in one housing, these sleeve bearings withstand heavy loads. Use them on round support rail shafts for applications that require maximum rigidity.
