Flanged Sleeve Bearings for Single Rails

Horizontal-Mount Flanged Sleeve Bearing for Single Rails

Side-Mount Flanged Sleeve Bearing for Single Rails

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.
