High-Temperature Linear Ball Bearings
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).
Stainless steel bearings are more corrosion resistant than steel bearings.

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).

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.
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 aluminum, chrome-plated steel, or 300 series stainless steel shafts. Frelon-lined 316 stainless steel bearings have excellent corrosion resistance. Note: Not for use with chrome-plated steel.

Tight-Tolerance Drive Rollers
The surface of these rollers is molded to a tolerance of either ±0.003 in. or ±0.08 mm to provide more consistent surface contact. Also known as contact wheels and feed rollers, they have tapped hubs that allow you to mount them onto a shaft or stud to transmit power. The urethane surface is nonmarring and wear resistant.
