Sprockets

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.

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

Plain Bore—Plain bore sprockets give you options—machine a custom bore, weld, or press-fit them in place. They're sized to the minimum shaft diameter listed and are machinable up to the maximum.

Flat Sprockets

Save space and cut weight—these sprockets don’t have a raised hub so they’re best for tight spots and lightweight designs. Bolt or weld them to components and mounting surfaces, or add a custom hub. Although they are versatile, they’re harder to align than sprockets with hubs.

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

Taper-Lock Bushing-Bore Sprockets


Sprocket Shown with Bushing (Sold Separately)	For Single Strand

Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Taper-lock bushings mount flush inside the sprocket hub for a slim profile. Mount a bushing (sold separately) on your shaft, slide the sprocket over it, and tighten the included set screws. As you tighten, the bushing grips the shaft and pulls it into your sprocket for a secure hold.

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.
