    Machinable Shaft Mount

    The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) sprockets and pulleys of the same bushing trade number. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
    304 Stainless Steel—304 stainless steel bushings resist corrosion from washdowns and humidity, so they’re common in food-processing plants and other frequently-cleaned areas. You can machine the center of these bushings to fit the exact dimensions of your shaft.

    Dry-Running Sleeve Bearings

    Image of Product. Front orientation. Sleeve Bearings. Dry-Running 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.
    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.
    Nylon—The most popular choice, nylon is wear resistant yet economical. Keep in mind, though, that it will swell and weaken when exposed to moisture.

    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.

    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.
    Moisture-Resistant Plastic Blend—Similar to UHMW, these bearings will keep their shape after washdowns but won’t hold up to steam cleaning. They're bright blue so they are easy to spot if they fall into your production line.

    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.

    Oil-Embedded Sleeve Bearings for Food and Beverage

    Image of Product. Front orientation. Sleeve Bearings. Oil-Embedded Sleeve Bearings for Food and Beverage.
    These lead-free bearings are infused with a food-grade oil that is odorless, colorless, tasteless, and safe for unintended contact with food. They’re often used in food and beverage processing, packing, and handling equipment. All are made from porous metal and saturated with oil to reduce maintenance and downtime. If you need a bearing rated for contact with food, consider dry-running sleeve bearings for food and beverage. All are fabricated, lubricated, and inspected in the U.S.

    Slide these collars from one end of your shaft and tighten the clamping screw. They grip firmly and evenly without marring the shaft, so you can reposition or remove them later.
    Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.
    303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.

    (Each Component Sold

    Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft. Tighten the clamping screws to secure. Good for precision motor and pump applications, the spider-shaped cushion reduces shock and compensates for minor shaft misalignment. Couplings allow zero backlash (no play).
    A complete coupling consists of two hubs and one spider (each component sold separately). Hubs are lightweight, corrosion-resistant aluminum. Spiders are polyurethane for fair vibration damping and good chemical resistance.
