    Ultra-Low-Friction Oil-Embedded Sleeve Bearings

    Image of Product. Front orientation. Sleeve Bearings. Ultra-Low-Friction Oil-Embedded 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.
    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.

    Drill Bushings for Extended-Length Drill Bits

    Guide extended-length drill bits into workpieces to create deep, accurate holes. Also known as gun drill bushings, these bushings are used with gun drilling machines and CNCs. Rather than installing them directly in your fixture, you slide these bushings in and out of sleeves (sold separately). This means you can replace a worn bushing quickly, without damaging your fixture. Swap in a bushing with a different ID, and you can use the same hole in your fixture for a different-sized bit.

    With ID tolerances sized specifically for reamers, these bushings ensure steady and precise hole finishing. Press them into a fixture plate with a manual or hydraulic press for permanent installation. Also known as headless bushings, these ANSI-type P bushings don’t need counterboring to be mounted flush. They are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.
