    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.
    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 Flanged Sleeve Bearings

    Image of Product. Front orientation. Contains Annotated. Flanged Sleeve Bearings. Dry-Running Flanged 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.
    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 PEEK—Get the strength of reinforced PTFE without compromising on heat resistance. With no additives, such as polyester fabric, PEEK bearings won’t melt at high temperatures. They’re also nearly as slippery and chemical resistant as plain PTFE.
    High-Load Moisture-Resistant Rulon LR—Won’t swell in wet or humid places, similar to acetal, but can support higher loads. These bearings also operate smoothly from cryogenic to oven-like temperatures.
    Ultra-Low-Friction Rulon J—These bearings glide effortlessly for applications with frequent starts and stops, such as conveyor systems.

    Dry-Running Sleeve Bearings for Food and Beverage

    Image of Product. Front orientation. Sleeve Bearings. Dry-Running Sleeve Bearings for Food and Beverage.
    Made of plastics permitted by the US FDA for contact with food, these bearings won’t release harmful, smelly, and distasteful impurities into your food or beverage production line. These self-lubricating plastics eliminate the need for oil, resulting in less maintenance and improved hygiene. You’ll find them inside food-processing equipment such as mixers, conveyors, and fillers.
    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.
    Ultra-Low-Friction Rulon 641—Get effortless motion with strength surpassing UHMW polyethylene. Rulon 641 bearings can also operate from cryogenic to oven-like temperatures.
