    Oil-Embedded Sleeve Bearings

    Image of Product. Front orientation. Sleeve Bearings. Oil-Embedded Sleeve Bearings.
    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.
    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.

    Needle-Roller Bearings

    Image of Product. Front orientation. Roller Bearings. Needle-Roller Bearings.
    Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.
    Open Bearing—Open bearings dissipate heat more efficiently than sealed bearings.

    These rollers are rated to handle radial and thrust (top and side) loads simultaneously. Also known as yoke-style cam followers, they have more mounting flexibility than threaded track rollers. They're typically mounted onto a shaft or clevis rod end. All rollers are permanently lubricated and have end seals to retain lubricant and protect rolling elements from dirt and contamination.

    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.

    The surface of these rollers is molded to a tolerance of either ±0.003 in. or ±0.08 mm to provide more consistent surface contact. Also known as contact wheels and feed rollers, they have tapped hubs that allow you to mount them onto a shaft or stud to transmit power. The urethane rubber surface is nonmarring and wear resistant.

    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.
