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.

Minimize shock loads—the thick side plates on this chain absorb jolts from motor startups, emergency braking, and sudden reversing. Like the chain on a bike, the side plates have a figure-eight shape that grips sprockets to transmit power between rotating shafts 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.

Steel with Through-Hardened Pins—Even stronger than standard steel chain, the pins in this chain are treated to withstand the most extreme shock loads.

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.

Add these links to your roller chain to attach brackets and guides, move items directly, or trip switches in conveying, timing, and aligning setups. Like the chain on a bike, the side plates have a figure-eight shape that grips sprockets to transmit power between rotating shafts without slipping. We offer compatible chain for your convenience. When using your own chain, make sure the trade numbers match. Do not use these links with our Low-Maintenance Roller Chain.

Forget the mess and the stress, this chain has bearings that run reliably with little or no need for lubrication. Like the chain on a bike, the side plates have a figure-eight shape that grips sprockets to transmit power between rotating shafts without slipping.

Oil-Embedded Open Bearings—Made from porous bronze saturated with oil, these bearings don’t require lubrication.

Steel—The go-to for roller chain, steel is strong and economical. It’s best for dry environments since moisture will cause it to rust.

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.

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.
