1.126" ID Bearings | McMaster-Carr

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.

Extreme-Load Heat-Treated Iron Copper—Our strongest oil-embedded sleeve bearings. They’re heat treated to form a uniform internal grain that makes them stronger than 863 iron copper. As a result, they’re often used to support extreme loads in earth-moving equipment and railroad applications. The increased iron content makes these bearings appear silver.

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.

Oil-Embedded Flanged Sleeve Bearings

Flanged sleeve bearings combine a sleeve and thrust bearing in one. The flange supports thrust loads and prevents the bearing from being pushed out of place. The sleeve is the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.

Light Duty Oil-Embedded Mounted Sleeve Bearings

With a two-piece housing made from thin pressed metal, these bearings are a cost-effective option when extreme precision isn't necessary. Less stable than bearings with forged, one-piece housings, they're good for hand-cranked systems, gravity feed conveyor rollers, and other low-speed applications. Made from porous, oil-saturated bronze, they release their own lubrication on startup, reducing the need for frequent relubrication.

With no moving parts, sleeve bearings stand up to dusty, dirty environments better than ball or roller bearings. However, with more friction generated, they're less effective at high speeds.

Steel Housing—Best for dry environments as moisture will cause them to rust.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.

Vibration-Damping Oil-Embedded Sleeve Bearings

These bearings quiet equipment by absorbing vibration. The rubber layer on the inside of these bearings flexes to align the shaft and reduce rattling. The bronze core is made from porous metal and saturated with oil to reduce maintenance and downtime. They’re used in compressors, engine mounts, and other vibrating equipment that suddenly starts and stops.

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 with 304 Stainless Steel Shell—The choice for most wet locations. These bearings won't corrode after washdowns and can stand up to most detergents and oil.
