1.2505" 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-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.

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.

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.

Extreme-Load Ultra-Chemical-Resistant Fiberglass-Backed PTFE—Our strongest PTFE bearings. They’re ideal for heavy loads thanks to a backing layer made of fiberglass. The PTFE core is unaffected by the harsh fluids that other plastics can't handle, including all strong acids and bases.

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.

Mold and Die Bushings

Guide pins, punches, and other components in molds and stamping dies—these bushings help you align the upper and lower halves of your setup.
