46.05mm 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.

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-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.

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.

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.

High-Strength 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.
