    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.

    High-Temperature Graphite-Lubricated Sleeve Bearings

    Image of Product. Front orientation. Sleeve Bearings. High-Temperature Graphite-Lubricated Sleeve Bearings.
    Made of a graphite and metal alloy, these bearings stay slippery at high temperatures where oil burns off and other bearings fail. With no need for refills, they require little to no maintenance. You’ll find them in pumps, propellers, and mixers that spin near steam or inside ovens. However, graphite may eventually flake off, dropping flecks and leaving smudges. If you need a spic-and-span space, consider dry-running bearings made of slippery plastic instead. All are fabricated, lubricated, and inspected in the U.S.

    The thick split spider on these couplings takes on twice as much torque as standard split spiders, while a set screw holds the hubs in place on your shaft. Also known as jaw couplings, use them to connect motors to pumps, mixers, and other high-torque equipment. You don’t need to lubricate them.
    For a complete coupling, you’ll need two hubs, one split spider, and a split spider cover (all sold separately).
    Hubs attach to the end of your shaft.
    Split spiders cushion between the two hubs to dampen vibration, reduce shocks, and handle shaft misalignment, extending the life of bearings, seals, and motors. You can replace them without having to remove the hubs or move your shaft and equipment around, which reduces the risk of needing to realign the shaft.
    Split spider covers hold the spider in place.

    Each hub includes a set screw (unless noted), which bites into your shaft to hold the coupling in place. Also known as Lovejoy® couplings, these three-piece couplings have a spider-shaped cushion between two hubs to reduce shock and handle minor shaft misalignment.
    A complete coupling consists of two hubs and one spider, or two hubs, one split spider, and one retaining ring (all components sold separately). Split spiders are easier to install and replace than standard spiders because there’s no need for tools or removing your hubs. Twist-lock them in place using a retaining ring.
    Buna-N—Buna-N spiders provide good vibration damping and chemical resistance.

    Keyless Locking Rigid Shaft Couplings for Overhung Loads

    Support the weight of a motor and transfer torque to another shaft at the same time with these couplings. Often used to hang motors from conveyor belts and other driven equipment, or to connect long sections of shafts, these couplings eliminate the need for support brackets. Use a torque arm to prevent hanging motors from spinning.
    The clamping screws on the coupling face squeeze two outer collars against an inner ring, pressing it tight against shafts to lock them together. This ring-locking mechanism leaves no room for backlash, meaning that all of the turning force created by the motor is passed on to the second shaft. These couplings grip shafts of any shape, so you can install them onto existing keyways and splines without using a key.
    To install these couplings, use a torque wrench to tighten each screw to the fastener tightening torque listed for each coupling size. To remove, gradually loosen each screw in sequence until you can slide the coupling on the shaft. Warning: Do not remove any clamping screws from the coupling until the outer collars are separated from the inner ring. The ring is under tension, and a sudden release of the collars can cause serious injury.
    Overhung load capacity is the amount of downward force that a coupling can withstand from a motor or other object that it is supporting. To calculate the overhung load, measure the distance from the center of the coupling to the center of gravity of the motor. Multiply that distance by the combined weight of the motor and the portion of the shaft between the coupling and the motor. Do not exceed the overhung load capacity for a coupling.

    Shaft Collars

    Image of Product. Front orientation. Shaft Collars.
    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.
    Zinc-Plated Carbon Steel—A step up from plain carbon steel collars, these withstand occasional exposure to moisture.
    303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.
    316 Stainless Steel—More corrosion resistant than 303 stainless steel collars. These collars withstand salt water and harsh chemicals, such as bleach, chlorine, and phosphoric acid.
    Aluminum—One-third the weight of steel and corrosion resistant.

    Strong-Grip Clamping Rigid Shaft Couplings

    These couplings have the gripping strength to handle higher torque than most other couplings. Couplings clamp evenly around the shaft to create a mar-free hold. Slide onto the end of your shaft and tighten the clamping screws to secure. Good for high-torque applications, rigid couplings connect two shafts that are aligned, allowing for no relative movement between the shafts.

    Two-Piece Rigid Shaft Coupling Bridges

    When your shafts are not close enough to use standard couplings, these have the length to bridge the gap. Install them anywhere on a shaft without removing components or having access to the ends of the shaft. Tighten the clamping screws to secure. Good for high-torque applications, rigid couplings connect two shafts that are aligned, allowing for no relative movement between the shafts.

    Hinged Shaft Collars

    Image of Product. Front orientation. Shaft Collars. Hinged Shaft Collars.
    Combine the versatility of a two-piece collar with the no-fuss installation of a one-piece design. These hinged collars swing open and shut onto your shaft when other components are already attached or you can't access the ends. The clamping screw is captive so it won't fall out, and it aligns itself in the hole when the collar swings shut.
