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

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.

Leaf Chain and Links

Chain

Pair with flat-belt pulleys for low-speed pulling and to counterbalance machine tools, elevator and oven doors, and forklift masts. Made of interlaced plates held together by rivet pins, leaf chain has a higher tensile strength than roller chain. Also known as counterbalance chain.

When servicing worn leaf chain, replace the entire chain—do not splice chain together or mix old and new chain.
