28.04mm 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.

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. Also known as Oilite® bearings.

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.

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.

High-Strength 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.

Oil-Embedded Flanged 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 incidental 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 direct contact with food, consider dry-running flanged sleeve bearings for food and beverage. All are fabricated, lubricated, and inspected in the U.S.
