0.752" 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.

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.

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.

841 Bearing Bronze—A classic choice for a starter pick. Also known as SAE 841 bearings.

Needle-Roller Thrust Bearings


Bearings	Washers

Small but mighty, our thinnest rolling thrust bearings slot into tight spaces and spin at whirring speeds. Their long, slender rollers support thrust loads and reduce friction in everything from machine tool spindles to gearboxes.

A cage holds the rollers in place. You can install these bearings without washers between hardened, ground surfaces for the thinnest profile. If you’re working with unhardened, unground surfaces, you’ll need two washers for the rollers to run on. This three-piece design is easy to lubricate, but the oil will attract dust and grime since it’s exposed.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

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 Steel Shell—The economical choice for dry environments where corrosion is not a concern. The carbon steel shell supports heavy loads but can’t resist rust as well as 304 stainless steel.

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.

Oil-Embedded Sleeve Bearings for Food and Beverage

These lead-free bearings are infused with a food-grade oil that is odorless, colorless, tasteless, and safe for unintended contact with food. They’re often used in food and beverage processing, packing, and handling equipment. All are made from porous metal and saturated with oil to reduce maintenance and downtime. If you need a bearing rated for contact with food, consider dry-running sleeve bearings for food and beverage. 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.

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.

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.

Extreme-Load Heat-Treated Iron Copper—Our strongest oil-embedded thrust 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 also makes them appear silver.

Dry-Running Sleeve Bearings

Made of naturally slippery plastic so you’ll never have to add lubricant. They’re ideal for clean environments where you need to prevent oil drips or graphite flakes. Compared to metal bearings, they are lighter and will never rust.

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.

MDS-Filled Nylon—A step up from standard nylon bearings. Upgraded with fine particles of molybdenum disulfide (MDS), these bearings have extra lubricity and wear resistance. However, they’re still nylon and will swell and weaken when exposed to moisture.

You can install and forget them since their porous surface releases oil over time. All are fabricated, lubricated, and inspected in the U.S.

If you need a bearing rated for direct contact with food, consider dry-running thrust bearings for food and beverage.
