Ultra-Thin Linear Sleeve Bearings
Thinner than standard linear sleeve bearings, these bearings fit where clearance is a concern. Pair them with round end-supported shafts. They have fixed alignment, so they’re best for applications where shaft misalignment is unlikely. The PTFE lining stands up to chemicals and won’t scratch the shaft. To install, slide them into a housing (not included).

Food Industry Linear Sleeve Bearings for Support Rail Shafts
These bearings for use in food applications also have excellent chemical and corrosion resistance. Mount them on a support rail shaft for applications requiring maximum rigidity. They have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure in place with two retaining rings (sold individually).

High-Load Mounted Linear Sleeve Bearings for Support Rail Shafts
With two bearings mounted in one housing, these sleeve bearings are designed to withstand heavy loads. Use them on round support rail shafts for applications that require maximum rigidity. All of these bearings have a ceramic-coated aluminum housing that’s lightweight and stands up to corrosion. They also have a slippery, chemical-resistant PTFE liner, so there’s no need for lubrication. These fixed-alignment bearings are for use where shaft misalignment is unlikely.

High-Load High-Speed Mounted Linear Sleeve Bearings for Support Rail Shafts
With two bearings mounted in a single housing, these bearings have higher load capacities than standard ones. A ceramic liner helps them achieve high speeds as well as rapid acceleration and deceleration. Mount these bearings on a support rail shaft for applications requiring maximum rigidity. Made of ceramic-coated aluminum, their housing is lightweight and corrosion resistant. These bearings are for fixed alignment, ideal for well-aligned shafts. Note: Not for use with ceramic-coated aluminum or 300 series stainless steel shafts.
