Sprockets

For Single 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.

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.

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

Needle-Roller

Bearing

Needle-Roller Bearing—These bearings rotate smoothly under your heaviest loads.

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.

Pair this chain with sprockets to transmit power between rotating shafts. Like the chain on a bike, the side plates have a figure-eight shape that grips the sprockets without slipping.

Lubrication is key to smooth operation and long chain life. Routinely apply oil by hand or install an oil dispenser for continuous lubrication.

Steel—The go-to for roller chain, steel is strong and economical. While proper lubrication helps prevent rusting, it’s not as corrosion resistant as coated or stainless steel.

Connecting Link—Use a single link to join both ends of your chain. Start by removing the spring clip from the link’s side plate. Then, slide the link pins into the mating rollers at each end of your chain and snap the clip back on. Also known as master links.

Adding Link—Attach with a connecting link to extend the length of your chain. Each link adds a length equal to the chain’s pitch. Also known as roller links.

Adding-and-Connecting Link—An all-in-one link for adding and connecting. It adds a half-pitch length at the roller end, allowing finer length adjustments than full-pitch links. The pin end connects to your chain—except for trade number 25, which requires a separate connecting link. Remove the side plate to install. Also known as half links and offset links.

No more hang-ups thanks to the flat, oblong side plates that create a level surface to keep items moving along conveyor lines. Unlike standard roller chain, there are no divots to snag products. Pair this chain with sprockets to transmit power between rotating shafts.

Lubrication is key to smooth operation and long chain life. Routinely apply oil by hand or install an oil dispenser for continuous lubrication.

Double Pitch—This chain has links that are twice as long as those on a single-pitch chain, making it lighter in weight and more energy-efficient over long drives. However, it operates at slower speeds. Use it with standard sprockets that have at least 24 teeth.

Steel—The go-to for roller chain, steel is strong and economical. While proper lubrication helps prevent rusting, it’s not as corrosion resistant as coated or stainless steel.

Corrosion-Resistant-Coated Steel—Combines the strength of steel with the corrosion resistance of stainless steel. The coating has been tested to withstand 500 hours of salt spray, so it holds up well in wet and outdoor conditions.

Corrosion-Resistant 304 Stainless Steel—Won't corrode from frequent washdowns and mild chemicals, including ammonia often found in cleaning solutions.

Adding Link—Attach with a connecting link to extend the length of your chain. Each link adds a length equal to the chain’s pitch. Also known as roller links.

Adding-and-Connecting Link—An all-in-one link for adding and connecting. It adds a half-pitch length at the roller end, allowing finer length adjustments than full-pitch links. The pin end connects to your chain. Remove the side plate to install. Also known as half links and offset links.

C2080H—Best for minimizing shock loads from abrupt starts and stops. The thick side plates on this chain absorb jolts from motor startups, emergency braking, and sudden reversing.

Add these links to your flat-edge roller chain to attach brackets and guides or move items directly in conveying, timing, and aligning setups. The flat, oblong side plates create a level surface that keeps items moving along conveyor lines. Unlike standard attachment links, there are no divots to snag or hang up products. We offer compatible flat-edge chain for your convenience. When using your own chain, make sure the trade numbers match.
