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.

Highly-Corrosion-Resistant 316 Stainless Steel—Our most corrosion resistant roller chain won’t degrade when exposed to salt water and harsh chemicals.

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.

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. Remove the side plate to install. Also known as half links and offset links.

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

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.

C2060H and 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.

Low-Maintenance Roller Chain and Links

Adding-and-Connecting

Links

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.

Sealed Bearings—These bearings come with seals to retain the grease you add and reduce the need for additional lubrication. They also keep grease off your equipment and prevent dirt from sticking to the chain.

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.

Corrosion-Resistant Nickel-Plated Steel—A step up from plain steel, the nickel plating adds a layer of rust protection in wet environments. However, if scratched, the underlying steel may still rust. The plating may also hinder welding.

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.

Roller Chain Link Assortments

Keep an assortment of extra links on hand for maintenance and repairs, from replacing worn links to adjusting your chain’s length.

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 and connects to your chain at the pin end, allowing finer length adjustments than full-pitch links. Remove the side plate to install. Also known as half links and offset links.

Hollow-Pin Roller Chain and Links

Adding-and-Connecting

Link

Slide rods or other attachments straight through the rollers. With hollow pins, there’s no need to take this chain apart or add attachment links like you would with standard roller chain. Pair the chain with sprockets to transmit power between rotating shafts. It’s commonly used in conveying applications.

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.
