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.

Mineral Oil Base—Mineral oil consistently lubricates at most temperatures but doesn’t last as long as synthetic oil.

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.

Hub-Mount Screw-Clamp Bushings

Transfer torque directly from a shaft to a hub. These bushings install over your hub to mount a sprocket, pulley, or gear to a shaft at the same time. Common in industrial gearbox applications, they can also connect a hollow shaft over a solid shaft. As screw-clamp bushings, they're good for shock loads. When you tighten the included clamping screws, the outer rings compress against a sprocket, pulley, or gear in between them, causing the inner rings to tighten around the shaft.

Oil-Embedded Thrust Bearings

Our simplest-to-use thrust bearings, with no moving parts and no need to lubricate. Their porous surface releases oil over time, so you can install and forget them. While they run in most conditions, oil may drip away if temperatures climb too high. For extremely hot environments, consider graphite-lubricated bearings. All are fabricated, lubricated, and inspected in the U.S.

841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.

High-Temperature Graphite-Lubricated Thrust Bearings

Keep parts spinning in temperatures as hot as 750° F. Lubricated with graphite, these bearings stay slippery where oil would burn off or solidify. You can install and forget them since the lubricant lasts forever. All are fabricated, lubricated, and inspected in the U.S.

Extreme-Temperature Chemical-Resistant Graphalloy—From the freezer to the furnace, these bearings glide in extreme temperatures where other bearings grind and fail. They withstand strong acids and bases found in cleaning fluids. They even work underwater without swelling or warping.

Set Screw Shaft Collars

Slide these traditional collars from one end of the shaft and tighten the set screw. They dig into the shaft for a secure hold, but one that leaves a gouge. For maximum holding power, make sure the set screw is harder than the shaft.

Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.

Zinc-Plated Carbon Steel—A step up from plain carbon steel collars, these withstand occasional exposure to moisture.

303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.

Aluminum—One-third the weight of steel and corrosion resistant.

Shaft Collars

Slide these collars from one end of your shaft and tighten the clamping screw. They grip firmly and evenly without marring the shaft, so you can reposition or remove them later.
