    Bearing

    Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.
    Open Bearing—Open bearings dissipate heat more efficiently than sealed bearings.

    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.
    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.
    Extreme-Load Heat-Treated Iron Copper—Our strongest oil-embedded sleeve 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 makes these bearings appear silver.
    Mineral Oil Base—Mineral oil consistently lubricates at most temperatures but doesn’t last as long as synthetic oil.
    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.

    Oil-Embedded Thrust Bearings

    Image of Product. Front orientation. Thrust Bearings. 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.
    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.
    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 run at slower speeds. The increased iron content also makes them 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 if the bearing heats up.

    Oil-Embedded Flanged Sleeve Bearings

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.
    Extreme-Load Heat-Treated Iron Copper—Our strongest oil-embedded flanged sleeve bearings. They’re heat treated to form a uniform internal grain that makes them stronger than 863 iron copper.

    Linear Sleeve Bearings

    Bearings are for use with round end-supported shafts. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).
    Self-Aligning with 2° Misalignment Capability
    Image of Product. Front orientation. Contains Annotated. Linear Bearings. Linear Sleeve Bearings , Self-Aligning, PTFE Liner.

    PTFE Liner

    Self-aligning bearings compensate for shaft misalignment.
    PTFE Liner—PTFE-lined bearings are chemical resistant and nonabrasive. They have a ceramic coating for added corrosion resistance.
    0.0015" Shaft Clearance—Bearings with 0.0015" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.

    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.
