Dry-Running Metal-Reinforced Plastic Sleeve Bearings
 |
Combine slippery plastic with the strength of metal. The PTFE core is naturally slippery, so you’ll never have to add lubricant. These bearings also keep your workspace clean with no lubricant to drip or flake and attract dust. Compared to all-metal bearings, they are lighter.
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.
PTFE with 17-4 PH Stainless Steel Shell—The highest load capacity of any sleeve bearing we offer. 17-4 PH stainless steel offers good corrosion resistance but is heavier than aluminum.

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.
High-Strength 863 Iron Copper—Iron makes these bearings harder, stronger, and more resistant to sudden starts and stops than 841 bearing bronze. However, they operate at slower speeds. The increased iron content makes these bearings appear silver.
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.
