0.5645" OD 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.

High-Load 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.

Flanged Sleeve Bearings

These bearings don’t come with a lubricant, so you can select the oil that meets the needs of your application. You’ll need to refill the oil, so make sure the bearing is located where you can access it. All are fabricated and inspected in the U.S.

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.

High-Load 932 Bearing Bronze—These bearings are strong enough for sudden starts and stops, plus they resist wear and tear. They are cast from an alloy of leaded tin bronze for uniform rigidity and strength. Also known as 660 leaded bronze bearings.

High-Load Chemical-Resistant 954 Bearing Bronze—The strongest of our bronze bearings. The addition of iron and aluminum makes them exceptionally strong and resistant to chemicals. They’re often used in the most demanding environments, such as salt mines. Also known as aluminum bronze.

High-Temperature Graphite-Lubricated Sleeve Bearings

Made of a graphite and metal alloy, these bearings stay slippery at high temperatures where oil burns off and other bearings fail. With no need for refills, they require little to no maintenance. You’ll find them in pumps, propellers, and mixers that spin near steam or inside ovens. However, graphite may eventually flake off, dropping flecks and leaving smudges. If you need a spic-and-span space, consider dry-running bearings made of slippery plastic instead. 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.

Ultra-Low-Friction Oil-Embedded Flanged Sleeve Bearings

Our slipperiest metal bearings, these are ideal for machinery with frequent starts and stops, such as conveyors. With nonstick PTFE particles added to the oil, they reduce friction to minimize wear and heat, so equipment runs more efficiently and lasts longer. All are fabricated, lubricated, and inspected in the U.S.
