    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 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.

    High-Torque Chain Couplings

    Image of System. Front orientation. Contains Annotated. Flexible Shaft Couplings. High-Torque Chain Couplings.
    A rugged roller chain locks onto teeth on the hubs to withstand high torque. Often found in conveyors, mixers, and crushers, these couplings also compensate for high angular misalignment. Lubricate to maintain smooth motion. For a complete coupling, select two hubs and one roller chain. Choose components of the same trade size to ensure they'll fit together.

    Floating Roller Chain Tensioners

    Image of ProductInUse. Front orientation. Contains MultipleImages. Chain and Belt Tensioners. Floating Roller Chain Tensioners.
    Mount these tensioners directly onto your chain drive. They have adjustable straps that take up slack and apply constant tension. Because they engage with the side plates instead of the rollers, they increase the life of your roller chain.
    UHMW Polyethylene—UHMW polyethylene tensioners are stronger and more durable than PTFE tensioners.
    Titanium—Titanium tensioners stand up to harsh and dirty environments. They're stronger and more durable than plastic tensioners. And with a low coefficient of friction, they work with chain that has little or no lubrication.
