Quick-Grip Screw-Clamp Bushings

Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed. As you tighten the collar nut, the inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.
Stainless steel bushings are corrosion resistant for use in harsh environments.

Flanged Screw-Clamp Bushings


A mounting flange prevents movement during tightening. These bushings are 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.

Hub-Mount Screw-Clamp Bushings


Transfer torque directly from a shaft to a hub. These bushings install over your hub to mount a sprocket, pulley, or gear to a shaft at the same time. Common in industrial gearbox applications, they can also connect a hollow shaft over a solid shaft. As screw-clamp bushings, they're good for shock loads. When you tighten the included clamping screws, the outer rings compress against a sprocket, pulley, or gear in between them, causing the inner rings to tighten around the shaft.

Corrosion-Resistant Flanged Screw-Clamp Bushings


Made from stainless steel or plated with nickel, these bushings resist corrosion. A mounting flange prevents movement during tightening. As screw-clamp bushings, they're good for shock loads. When you tighten the clamping screws, the bushing's inner sleeve tightens onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.
Nickel-plated steel bushings have good corrosion resistance in wet environments. However, the plating may begin to flake with long-term use.
Stainless steel bushings have excellent corrosion resistance and can withstand prolonged exposure to moisture.

Corrosion-Resistant Flush-Mount Screw-Clamp Bushings


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.

Grommets for Flexible Plastic Conduit

Preventing wear and cracks, these grommets shield the sections of your conduit that rub and bang against nearby components. They’re also known as wear rings and abrasion rings. Use them in applications where machinery vibrates, conduit is dragged across a surface, and robots move dynamically. They have a two-piece construction, so you can attach them to any part of the conduit without disrupting your system. To make sure they stay in place without compressing the conduit and damaging the cables inside, they have internal grooves that hug the conduit’s ridges.
