Duplex Chain

Roller Chains, also referred to as bush roller chains have a drive chain and chain links that joined together make up the roller chain. A roller chain consists of a pin, bushing, roller, pin link plate and roller link plate.They are used in a wide range of applications including the transmission of mechanical power with machinery such as industrial conveyors, printing presses and vehicles such as cars, motorbikes and bicycles. They are also used in the food industry, mining, automotive, warehouse and distribution, agriculture, and forestry.

How do Roller Chains Work?

They have a typical chain link structure, a series of cylindrical rollers connected by links. They utilise a wheel component with teeth known as a sprocket to drive the chain when rotated, which in turn provides the power transmission. Roller chains are available in a rage of sizes and standards.Roller chains are available in materials such as steel, stainless steel, carbon steel and others. The 3 most common types are a simplex, consisting a single row of roller chain links, duplex, featuring a double row of chain links and triplex which consist of three rows of links.The pitch of the chain refers to the distance between links and is the measurement from one roller pin centre to the other. Smaller pitch chains run smoother than larger pitch chains.
