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.

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.

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.

Pin—The pins are extended to trip switches.

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

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.

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.

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.
