1.7515" 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.

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.

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.

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.
