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.

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.

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.

Dry-Running Roller Chain and Links

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.

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.

Flexible Roller Chain and 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.

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.

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.
