Roller Chain and Links


Adding Links	Adding-and-Connecting Links

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 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.

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.

Low-Maintenance Roller Chain and Links

Adding-and-Connecting

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.

Adding Links

SK-1 Attachment

Add these links to your flat-edge roller chain to attach brackets and guides or move items directly in conveying, timing, and aligning setups. The flat, oblong side plates create a level surface that keeps items moving along conveyor lines. Unlike standard attachment links, there are no divots to snag or hang up products. We offer compatible flat-edge chain for your convenience. When using your own chain, make sure the trade numbers match.

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.

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.

Tab—The tabs have holes to mount parts and hang hooks.

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.

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.

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.

Clog-Resistant Flat-Edge Roller Chain and Links


Adding Links	Adding-and-Connecting Links

Debris falls through this chain, so it doesn’t jam the rollers and bring everything to a halt. Originally designed to move lumber while letting splinters and sawdust drop to the floor, this chain has the largest roller spacing in our offering. Flat, oblong side plates create a level surface that keeps items moving along conveyor lines with no hang-ups. Unlike standard roller chain, there are no divots to snag products. Pair this chain with sprockets to transmit power between rotating shafts.

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.
