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.
High-Strength Ultra-Chemical-Resistant Polyester Fabric-Reinforced PTFE—Woven polyester resin reinforces these PTFE bearings to support loads and speeds comparable to metal bearings. Similar to other PTFE options, they are unaffected by the harsh fluids that other plastics can't handle, including all strong acids and bases.

Oil-Embedded Sleeve Bearings
 |
Install and forget these self-lubricating bearings. All are made from porous metal and saturated with oil to reduce maintenance and downtime. A good all-around choice, they are used in everything from palm-sized fans in
electronics to tire-sized pulleys. Although these bearings will work in most conditions, oil may drip away if temperatures get too high. Consider a graphite-lubricated bearing for higher temperatures or places where you can’t
afford the mess. All are fabricated, lubricated, and inspected in the U.S.
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.
841 Bearing Bronze—A classic choice for a starter pick. Also known as SAE 841 bearings.
Synthetic Oil Base—A high-quality lubricant makes all the difference. Synthetic oil is less sensitive to temperature changes than mineral oil, so it won't get runny and leak away at higher temperatures. Also known as Oilite® bearings.
