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.

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

Taper-Lock Bushings

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 trade number. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.

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.

Machine Key—Bushings with a machine key fit into a matching keyway on a sprocket or pulley for high-torque applications.
