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.

304 Stainless Steel—304 stainless steel bushings are corrosion resistant for use in harsh environments.

Grounding Conduit Clamps

Grounding

Clamp with

Hinge

Ground conduit by running a ground wire through the attached lug. The included grommet protects wire and cable from abrasion when being pulled. Use with medium-wall (IMC) and thick-wall (rigid) steel conduit.

Hinge—Grounding clamps with hinge open for quick installation around conduit and secure with a screw.

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.

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—Nickel-plated steel bushings have good corrosion resistance in wet environments. However, the plating may begin to flake with long-term use.

Stainless Steel—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.

Flexible Plastic (MPT) Conduit and Fittings

Bend, twist, and wrap machine wiring through tight spaces. Corrugated like ENT, this conduit is more resilient against repeated flexing. Pair it with compatible fittings to seal out liquid and protect wiring indoors and outdoors. Conduit and fittings are made of nylon to resist moisture and chemicals.

Conduit Bumpers

Screw-Clamp

Connection

Prevent wear and cracks by shielding sections of conduit that rub and bang against nearby components. Also known as wear rings and abrasion rings, use these bumpers where machinery vibrates, conduit is dragged across a surface, and robots move dynamically.
