Sprockets

For Double Strand |
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.
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.

High-Misalignment Tire Couplings
 |
With a large, flexible rubber tire, these withstand the highest misalignment of any coupling while reducing vibration. For a complete coupling, select two hubs, one tire, and two bushings. Choose components of the same trade size to ensure they'll fit together.
Hubs
 |
The metal body mounts onto shafts to transmit torque from one shaft to the other through the flexible center.
Iron and Steel Hub—Best for dry environments, since moisture will cause these hubs to rust.
Clamp-On Shaft Mount—Grip shafts evenly without marring them and hold tighter than set screws. Tighten the clamping screws to secure.
Tires
 |
Fit these highly flexible rubber tires over the two hubs. They transmit torque, compensate for misalignment, and isolate shock and vibration.
Buna-N—Highly tear resistant.

Quick-Disconnect (QD) Bushings
 |  |
Clamp-On Shaft Mount |
The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) 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.

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.
