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.

Connecting Link—Use a single link to join both ends of your chain. Start by removing the spring clip 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.

Extra Heavy Duty Chain for Lifting

Lift, hoist, and rig heavy equipment, vehicles, containers, and more with the strongest chain we offer. This chain is graded by weight capacity, so you can pick the best option whether you're hauling a bulldozer or unloading cargo from a ship. Look for the manufacturer's stamp on each link to confirm the grade.

When using fittings with chain, match the trade size and meet or exceed the chain’s grade to avoid chain damage or failure.

Warning: Never use chain to lift people or items over people.

Grade 80 Chain—Your go-to option for most lifting jobs. Rig and lift industrial vehicles, heavy machinery, and shipping containers with this chain.

Grade 100 Chain—For exceptionally heavy lifting jobs. It's approximately 25% stronger than Grade 80 chain to handle larger loads and continuous lifting tasks in settings such as construction and mining.

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

Black Painted Steel—Best for dry environments as paint may chip and corrode over time.

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

Wear Gauges

Measure the maximum amount of wear allowed by OSHA on links of Grade 80 or 100 steel chain. If you can insert the gauge over any part of the link, you should take the chain out of service.
