About Sleeve Bearings

Choose a sleeve bearing that matches your load and speed requirements and that's right for your environment.

Dry-Running Sleeve Bearings

Made of naturally slippery plastic so you’ll never have to add lubricant. They’re ideal for clean environments where you need to prevent oil drips or graphite flakes. Compared to metal bearings, they are lighter and will never rust.

With no moving parts, sleeve bearings are the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.

Extreme-Load Ultra-Chemical-Resistant Fiberglass-Backed PTFE—Our strongest PTFE bearings. They’re ideal for heavy loads thanks to a backing layer made of fiberglass. The PTFE core is unaffected by the harsh fluids that other plastics can't handle, including all strong acids and bases.

Electrically Insulating Linear Sleeve Bearings

These fiberglass bearings are lightweight, nonmagnetic, and won’t conduct electricity. Bearings are for use with round end-supported shafts. All have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).

Fixed Alignment

0.001" Shaft Clearance—Bearings with 0.001" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.
