2.001" ID Bearings | McMaster-Carr

Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.

Open Bearing—Open bearings dissipate heat more efficiently than sealed bearings.

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.

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.

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

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.

Extreme-Load Heat-Treated Iron Copper—Our strongest oil-embedded flanged 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.

Ejector Pin Bushings

Eject parts smoothly from your mold. These bushings reduce friction between your ejector pins and plates, so they slide easily and wear out slowly. An external channel directs lubricant into these bushings, so you don’t need to line up your nozzle with the lubrication hole. Once the lubricant is inside, a figure-eight-shaped groove distributes it evenly along the surface.
