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

Corrosion-Resistant Flange-Mounted Linear Ball Bearings
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.

High-Speed Flange-Mounted Linear Sleeve Bearings
A ceramic liner makes high speeds as well as rapid acceleration and deceleration possible. The flange-mount design is good for vertical linear motion applications. Bearings are for use with round end-supported shafts and are self-aligning to compensate for shaft misalignment. End seals keep contaminants out.

Chemical-Resistant Flange-Mounted Linear Sleeve Bearings
The Frelon liner on these bearings allows them to stand up to a wider range of chemicals than other flange-mounted linear sleeve bearings. All are self-aligning to compensate for shaft misalignment and are for use with round end-supported shafts. Note: Not for use with bare aluminum or chrome-plated shafts.
Bearings with 0.0005" shaft clearance are best for precision applications. Bearings with 0.0015" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.

Threadless Lead Screw Nuts
Install these nuts on a rotary shaft to create a linear positioning system without a lead screw. Instead of threads, a set of angled ball bearings drives the nut along a shaft as it spins. Nuts move towards you when the shaft rotates clockwise and away from you when the shaft rotates counterclockwise. To prevent overload damage, these nuts can be adjusted to slip and stop travelling at a given thrust load. Thrust loads are loads that are applied parallel to the shaft. Bearings are permanently lubricated to save maintenance time and effort.
Travel distance per turn is the distance the nut moves with one revolution of the shaft.

Bearings are lined with slippery, durable plastic and have no moving parts. They work well in automated systems and other applications requiring precise, repetitive motion. They withstand exposure to dirt, water, impact, and vibration.
Heavy duty bearings work well for pick-and-place, parts-transfer, and other high-speed applications with frequent starts and stops.
Bearings with a flanged profile have through holes for mounting loads to the bearing.
Bearing pads replace worn pads. Hand brakes hold sleeve bearing carriages in place on the rail. Carriages for double rails and 1", 1 1/2", and 40mm single rails have a mounting hole for the brakes.
