About Linear Bearings

Bearing with Retaining Ring Grooves

Bearings are for use with round end-supported shafts. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).

Bearings with end seals keep lubricant in and dust out.

Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.

Fixed-alignment bearings are for use where shaft misalignment is unlikely.

High-Temperature Linear Ball Bearings

Bearing with Retaining Ring Grooves

The choice for low-friction motion in high-temperature environments. Bearings are for use with round end-supported shafts and have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).

Dust-Resistant Linear Sleeve Bearings

Aluminum Self-Aligning Bearing

PTFE Fixed Alignment Bearing

Aluminum Fixed Alignment Bearing

Ridges on the inside of these bearings wipe away dust and debris. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually). All bearings are lined with lightweight, corrosion- and chemical-resistant PTFE.

Self-aligning bearings compensate for shaft misalignment. Fixed-alignment bearings are designed for use with round, end-supported shafts where shaft misalignment is unlikely.

6061 aluminum bearings have good corrosion resistance, and have a higher load capacity than bearings made entirely of PTFE.

Linear Ball Bearings for Support Rail Shafts

Mount these bearings on a support rail shaft for applications requiring maximum rigidity. All have end seals to keep lubricant in and dirt out. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).

Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.

Fixed-alignment bearings are for use where shaft misalignment is unlinkely.

Corrosion-Resistant Flange-Mounted Linear Ball Bearings

Round Flange

Square Flange

The bearing, housing, and balls of these mounted bearings are stainless steel for excellent corrosion resistance. The flanged housing is good for vertical linear motion applications. All bearings are for use with round end-supported shafts and have a fixed-alignment design for use where shaft misalignment is unlikely. End seals keep lubricant in and dirt out.
