Sprockets

Finished Bore

Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.

Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.

Wear-Resistant Steel with Hardened Teeth—These sprockets have teeth that are hardened from the tip to the base so they withstand chain contact and wear evenly. That means fewer broken teeth and a longer lifespan than sprockets with unhardened or tip-hardened teeth. Steel is best for dry environments since moisture will cause it to rust.

Corrosion-Resistant 18-8 Stainless Steel—Won't corrode from frequent washdowns and mild chemicals, including ammonia often found in cleaning solutions.

Finished Bore—Mount these sprockets onto your shaft and secure with a set screw—no machining required.

Idler Sprockets

Maintain constant tension on your roller chain to reduce wear and vibration. These sprockets press against the chain to take up slack and rotate freely on bearings to keep the chain moving smoothly. They’re often paired with roller chain tensioners.

For Single Strand

Sleeve Bearing

Sleeve Bearing—With no moving parts, sleeve bearings are best for dirty environments. They generate more friction than ball bearings, making them less suitable for high-speed applications. Made of porous bronze embedded with oil, all are self-lubricating.

Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.

Get more power with less noise. These sprockets mesh perfectly with inverted-tooth chain—running faster and more quietly than roller chain while also transferring more power. All are made in the U.S.

Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.

Split-Tapered Bushings

Steel

The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings. They're for use with split-tapered sprockets and pulleys of the same bushing trade number. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.

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.

Quick-Grip Flanged Hydraulic Bushings

Tighten just one set screw to clamp these bushings evenly around your shaft. The screw forces hydraulic fluid in between the double-walled sleeve, expanding the two walls against the shaft and the hub of your sprocket, pulley, or gear for a tight hold. Since you don’t have to tighten multiple screw clamps individually, these bushings are quick to adjust and more likely to stay aligned on your shaft. They’re also good for shock loads. A mounting flange prevents movement during tightening. Use a hex key to tighten.

Note: To avoid deforming the sleeve walls, make sure to fully tighten the screw.

17-4 PH Stainless Steel—17-4 PH stainless steel bushings have excellent corrosion resistance in most environments.
