    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.
    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.
    Connecting Link—Use a single link to join both ends of your chain. Start by removing the spring clip or cotter pin 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-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.

    High-Accuracy Roller Chain Wear-Indicating Gauges

    Image of ProductInUse. Front orientation. Contains Annotated, MultipleImages. Chain Wear Gauges. High-Accuracy Roller Chain Wear-Indicating Gauges.
    Precisely measure chain elongation to see if you need to replace your chain. These gauges give a more accurate reading than alternatives because they’re designed to anchor to a roller and extend across several links. A color indicator helps you quickly measure the space between rollers. If the gauge rests on top of the chain and you see green markings, your chain doesn't need to be replaced. If it slips between two rollers and you only see red markings, it’s time for a replacement.

    Sprockets

    Image of Product. Plain Bore. Front orientation. Drive Sprockets. Sprockets, For Single Strand, Plain Bore.

    Plain 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.
    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.

    Ball Bearing

    Ball Bearing—Smoother than smooth—the balls inside these bearings roll nearly friction-free to handle high speeds. All are sealed to keep lubricant in and dust out.
    Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.

    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.
    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.
    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.
