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.
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.
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 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

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.

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.
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.

Shown Installed (Sprockets Not Included) | Chain |
This chain smoothly transmits power between rotating shafts with minimal vibration and noise. The shape of the teeth and pins make the chain interlock with a sprocket better than a roller on a roller chain, which means this chain can move faster and transfer more power than roller chain. To connect the two free ends together, align the holes in the link plates and insert the included connecting pins. Choose a sprocket (not included) that matches the inverted tooth chain trade size of your chain.

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.
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.

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.
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.
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.

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.

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.
