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.
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.

Drive out chain pins with a twist of the handle. Breakers allow you to disassemble chain in order to remove or add links.
ANSI Roller Chain Wear-Indicating Inserts
 |
Place these steel inserts between two roller links. If they can be inserted past your ANSI number, the chain is worn out.

Floating Roller Chain Tensioners
 |
Mount these tensioners directly onto your chain drive. They have adjustable straps that take up slack and apply constant tension. Because they engage with the side plates instead of the rollers, they increase the life of your roller chain.
UHMW Polyethylene—UHMW polyethylene tensioners are stronger and more durable than PTFE tensioners.
PTFE—PTFE tensioners handle temperatures up to 450° F, more than twice as high as UHMW and titanium models.
Titanium—Titanium tensioners stand up to harsh and dirty environments. They're stronger and more durable than plastic tensioners. And with a low coefficient of friction, they work with chain that has little or no lubrication.

Jaw-End Roller Chain Pullers
 |
Knob Handle |
These pullers grip both ends of a roller chain and draw them together so you can add or remove a link without fighting chain tension. They eliminate the need for a second person to hold chain ends in alignment, making field repairs and resizing faster.
