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 style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.

Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws. They are for use with taper-lock sprockets of the same bushing style. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.

A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket. They are also good for shock loads. When you tighten the included 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.

Insert these bushings into the bore of your sprocket for flush or recessed mounting. They handle shock loads and have higher torque ratings than self-centering bushings. 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.

Tighten the set screw to bite into an unhardened shaft for a secure hold. The two-piece design allows you to install these collars anywhere on a shaft without removing components or having access to the ends of the shaft. Clamping screws provide extra grip.

Carbon steel collars are strong and wear resistant. Their black-oxide finish is somewhat corrosion resistant, but only in dry environments. Their dark color can be useful for matching other parts in your system.

303 stainless steel collars are corrosion resistant and highly machinable.

Install these collars anywhere on a shaft without removing components or having access to the ends of the shaft. Because they’re grade 1018 carbon steel, you can easily weld them to other components. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.

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.

Buna-N spiders provide good vibration damping and chemical resistance. Hytrel spiders provide fair vibration damping and excellent chemical resistance.

The thick split spider on these couplings can take on twice as much torque as standard spiders, extending the life of bearings, seals, and motors. They are often used to connect motors to pumps, mixers, large conveyors, and other high-torque equipment. To assemble a complete coupling, you will need two hubs, one split spider, and a split spider cover (all sold separately). They are also known as jaw couplings.

The hubs connect to your shaft with a set screw, which bites into the shaft and holds the hub in place. They are keyed and bored to standard ANSI/AGMA 9002 dimensions and tolerances, which means they fit snugly on standard shaft sizes. Spiders act as a cushion between the two hubs, reducing vibration and compensating for slight shaft misalignment. No need to remove hubs, disconnect shafts, or move equipment to replace worn split spiders—they are split along one side for easy installation and removal. The split spider cover sits on top of the spider to hold it in place, completing the coupling.

These split spiders are all urethane, which holds up to repeated abrasion and is difficult to tear. Spiders with a medium-soft hardness rating are the most common choice for these couplings. Their softness allows them to absorb the most vibration. Spiders with medium hardness rating can handle higher torque than the soft spiders, but are not as good at damping vibration. Spiders with a max. temperature of 350° F hold up better near ovens and other hot equipment.

A ceramic liner makes high speeds as well as rapid acceleration and deceleration possible. Bearings are for use with round end-supported shafts. They have a fixed-alignment design for applications where shaft misalignment is unlikely. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).

With a grooved inner diameter, these bearings are designed to work with splined shafts. Together, they transmit rotary power while allowing the bearing to move freely along the length of the shaft. All are for use where shaft misalignment is unlikely.

Also known as ball splines, ball bearings run with less friction than plain bearings, so they're smoother and more precise, even at high speeds. However, they don't transmit as much torque as plain bearings. They're commonly used for robotic systems and other automated applications that require complex, fast movements.
