    Sleeve Bearings

    Image of Product. Front orientation. Sleeve Bearings. Sleeve Bearings.
    These bearings don’t come with a lubricant, so you can select the oil that meets the needs of your application. You’ll need to refill the oil, so make sure the bearing is located where you can access it. All are fabricated 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 932 Bearing Bronze—These bearings are strong enough for sudden starts and stops, plus they resist wear and tear. They are cast from an alloy of leaded tin bronze for uniform rigidity and strength. Also known as 660 leaded bronze bearings.

    Spider Couplings

    Image of System. Front orientation. Contains Annotated. Flexible Shaft Couplings. Spider Couplings.
    With two hubs gripping a rubbery spider in the center, these couplings damp vibration and transfer torque while flexing to handle misaligned shafts. The metal hubs never touch each other, so there's no need for lubrication. Also known as Lovejoy® couplings. For a complete coupling, select two hubs and one spider or two hubs, one split spider, and one retaining ring. Choose components with the same trade size to ensure they'll fit together.
    Hubs
    Image of Product. Front orientation. Flexible Shaft Couplings. Spider Couplings, Hubs.
    The metal body mounts onto shafts to transmit torque from one shaft to the other through the flexible center.
    Keyed—Mount onto shafts with a matching keyway.
    Steel—Best for dry environments, since moisture will cause these hubs to rust.

    Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads. When you tighten the included clamping screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.

    High-Torque Spider Couplings

    Image of System. Front orientation. Contains Annotated. Flexible Shaft Couplings. High-Torque Spider Couplings.
    With a thick split spider in the center, these transmit higher torque than standard split spider couplings. Connect them to pumps, mixers, and other equipment that generates heavy torque. The spider also prevents metal-to-metal contact between the hubs, so there's no need for lubrication. For a complete coupling, select two hubs, one split spider, and one split spider cover. Choose components with the same trade size to ensure they'll fit together.

    Unlike standard spiders, you can install these without using tools, removing hubs, or realigning shafts. Hold them in place with a retaining ring.
    Urethane Rubber—Tough, with plastic-like tear resistance. Higher-durometer spiders are more rigid for more precise positioning, but they absorb less vibration.

    Insert these nickel-plated steel bushings into the bore of your sprocket for flush or recessed mounting in wet environments. When you tighten the included clamping screws on these bushings, their inner sleeve contracts onto the shaft and their outer sleeve expands to hold your sprocket, pulley, or gear. This keeps bushings from slipping during sudden starts and stops.

    Slide these traditional collars from one end of the shaft and tighten the set screw. They dig into the shaft for a secure hold, but one that leaves a gouge. For maximum holding power, make sure the set screw is harder than the shaft.
    Zinc-Plated Carbon Steel—A step up from plain carbon steel collars, these withstand occasional exposure to moisture.
    Blue Passivated Zinc-Plated Carbon Steel—Withstand moisture and mild chemicals better than standard zinc-plated-steel collars. The blue passivated finish makes it easy to identify metric collars at a glance.
    Carbon Steel—Strong and easy to machine. Use in dry environments, since moisture will cause steel to rust.
    303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.
