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.

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

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

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.

Flexible Roller Chain and Links

Chain

Connecting Links

Thanks to extra space between components, this chain flexes side to side to take on misaligned sprockets or curved conveyor paths. 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. Also known as bow chain.

Lubrication is key to smooth operation and long chain life. Routinely apply oil by hand or install an oil dispenser for continuous lubrication.

Quick-Connect Roller Chain

Snap this chain together without links, tools, or headaches. Made of plastic, it’s lightweight, quiet-running, and resistant to mild chemicals. It also runs smoothly without lubrication. However, it handles only a fraction of the load of all-metal chain. 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.

Dry-Running Roller Chain and Links

Chain

Connecting Link

Say goodbye to messy grease and time-consuming maintenance. This chain has plastic bearings that run smoothly without lubrication. Paired with stainless steel pins and side plates, it’s lightweight, quiet-running, and resistant to mild chemicals. The chain withstands starts and stops better than all-plastic chain, but it handles only a fraction of the load of all-metal chain. 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.
