1.2535" ID Bearings | McMaster-Carr

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.

841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.

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.

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.

Mineral Oil Base—Mineral oil consistently lubricates at most temperatures but doesn’t last as long as synthetic oil.

Ultra-Low-Friction Oil-Embedded Thrust Bearings

Our slipperiest metal thrust bearings glide on machines with frequent starts and stops, such as conveyors. Their oil contains nonstick PTFE particles that reduce wear and heat, extending the life of your equipment. All are fabricated, lubricated, and inspected in the U.S.

841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.

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 if the bearing heats up.
