Leaf chains are a type of roller chain used in mechanical power transmission applications that require high strength and durability. They are made up of straight, flat plates that are connected by pins, allowing them to pivot and articulate around each other. The plates are typically thinner than those used in standard roller chains, which makes leaf chains more flexible and able to bend around smaller sprocket diameters.

Leaf chains are commonly used in heavy-duty equipment such as forklifts, cranes, and conveyors. They are able to handle high loads and resist wear and fatigue, making them ideal for applications that require a reliable and durable power transmission solution.

There are several different types of leaf chains, including:

AL series: This is the most common type of leaf chain and is designed for general-purpose use. It is available in a range of sizes and can be used in a variety of applications.

BL series: This is a heavier-duty version of the AL series and is designed for applications that require higher strength and durability.

LL series: This is a lighter-duty version of the AL series and is designed for applications where weight is a concern.

LH series: This is a heavy-duty version of the LL series and is designed for applications that require high strength and durability, but where weight is still a concern.

Leaf chains are typically used with sprockets that have straight teeth, as opposed to the curved teeth found on standard roller chain sprockets. This is because the flat plates of the leaf chain require a flat surface to engage with. Proper lubrication is also important for maintaining the performance and longevity of leaf chains.
