Linear Sleeve Bearings for Support Rail Shafts
Mount these bearings on a support rail shaft for applications requiring maximum rigidity. 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. 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.
