Roller Chain and Links


Chain

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.

Heavy Duty Roller Chain and Links

Chain

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.

Jack Chain

Hang all sorts of small signage and fixtures with our lightest duty chain. With the links formed into a figure eight, then twisted into a 90° angle, it won't spin or jostle in the wind.

Warning: Not for overhead lifting.

Zinc-Plated Steel—A common and economical choice, the zinc plating resists occasional moisture.

Nickel-Plated Steel—With a shiny silver finish, the plating also withstands mild chemicals and salt water without wearing away as fast as zinc-plated steel.

Brass-Plated Steel—Often chosen for the shiny gold finish, the plating also keeps out occasional moisture.

Corrosion-Resistant 304 Stainless Steel—With solid stainless steel construction, this chain has no plating that could wear away. It won't rust in wet environments and holds up against mild chemicals and solvents.

Brass—With a shiny gold finish, brass is also more durable than plated steel and won't rust in wet environments.

Sash-Chain Lanyards—Not for Lifting

The chain has flat links that fold back on themselves for maximum flexibility. Use the split ring on one end to hold tags and keys.

Zinc-Plated Steel—Zinc-plated steel lanyards are mildly corrosion resistant.

18-8 Stainless Steel—18-8 stainless steel lanyards are more corrosion resistant than zinc-plated steel lanyards.

Register Chain

Open and close furnace doors, vents, and skylights in hard-to-reach spots. The cut ends of each link interlock onto the next one, making it strong but easy to pry open to add more links.

Warning: Not for overhead lifting.

Steel—Best for dry environments since moisture will cause this chain to rust.

Zinc-Plated Steel—A common and economical choice, the zinc plating resists occasional moisture.
