About Linear Bearings
More
Linear Ball Bearings
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-Load Linear Ball Bearings
Designed to handle heavy loads, these bearings have higher load capacities than comparable standard linear ball bearings. They are for use with round end-supported shafts and have a self-aligning design to compensate for shaft misalignment. 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.
Bearing with stainless steel balls is more corrosion resistant than bearings with steel balls.

Linear Sleeve Bearings
Bearings are for use with round end-supported shafts. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).
Bearings with 0.0005" shaft clearance are best for precision applications. Bearings with 0.001" or 0.0015" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.
Self Aligning—Bearings compensate for shaft misalignment.
Fixed Alignment—Bearings are for use where shaft misalignment is unlikely.
Frelon-lined bearings are wear and chemical resistant. Frelon-lined aluminum bearings have good corrosion resistance. Note: Not for use with bare aluminum, chrome-plated steel, or 300 series stainless steel shafts.
PTFE-lined bearings are chemical resistant and nonabrasive. They have a ceramic coating for added corrosion resistance.

Dust-Resistant Linear Sleeve Bearings
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.
