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.

Three tapped counterbored holes and three unthreaded holes provide mounting flexibility. Collars clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screws to secure.

Collars with keyway have a standard ANSI keyway for use with keyed shafts, keys, and key stock.

Black-oxide steel collars are stronger than aluminum and stainless steel collars. They have some corrosion resistance. Aluminum collars are lightweight and have good corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.

Two tapped holes on the face of these collars allow you to fasten them to gears, pulleys, and sprockets. Collars clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screw to secure.

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.

One end has a finished bore size; the other can be machined to any size—great for connecting to uncommon shaft sizes and shafts that are undersized from wear or oversized from coatings. Slide these couplings onto your shafts and tighten the clamping screws for a secure hold that won’t damage the shafts. All of these couplings are rigid and must be used on aligned shafts. They prevent movement between the shafts, so they can handle high-torque applications.

Couplings for keyed shafts have keyways that firmly grip the shaft’s key to eliminate slipping. They handle higher torque than couplings for round shafts.

Steel couplings are a good option in dry environments.

303 stainless steel couplings resist corrosion caused by water. They're good for wet and damp environments but will corrode when exposed to salt water and other chloride solutions.

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.

Access one shaft without disconnecting the other. These rigid couplings have a solid bottom that connects the shafts and two top pieces that clamp the shafts independently.

Black-oxide steel couplings are stronger than stainless steel couplings but should be used in primarily dry environments since they may rust.

Stainless steel couplings withstand continuous exposure to water and chemicals, such as in pumping applications.
