Leaf Chain

Chain consisting of just link plates and pins. Also called balance chain.

Comes in two types: AL Series for light loads, and BL Series for heavy loads. Their dimensions and link plate formations are different.

*Special clevises and sheaves are required when using Leaf Chain.

Leaf Chain

Structure

Leaf Chain consists of just link plates and pins. The plates are connected by pins, which receive the tensile forces acting on the chain. The outer plates form a press-fit with the pins, which are riveted.

Meanwhile, the inner plates and middle plates form a slip fit with the pins. The pins pass between the plates and receive the shear forces and slide within the inner plate hole when the chain articulates.

Leaf Chain Structure
*Press fit
When the shaft is fitted to the hole, it forms a constant interference fit. The hole's tolerance range is entirely lower than the shaft's tolerance range.
*Slip fit
When the shaft is fitted to the hole, there is a constant gap in the fit. The hole's tolerance range is entirely greater than the shaft's tolerance range.

End fittings

Connecting links, end links, outer links, and inner links can all be used for Leaf Chain end fittings.

End fittings type

1. Connecting link 2. End link
3. Outer link 4. Inner link

Clevises, End pins, and Sheaves

Check and supply the following clevises, end pins, or sheaves for your end fitting connection. Contact a Tsubaki representative with any clevis or end pin requests.

Product Types/Features
AL Series

AL Series

Used mainly with light loads. The outer shape and plate thickness of AL Series plates are the same as for RS Roller Chain outer plates in the equivalent pitch. The pin diameter is roughly the same as with RS Roller Chain as well.

BL Series

BL Series

Used mainly with heavy loads. The plate width of BL Series is the same as for RS Roller Chain inner plates of equivalent pitch, but the plates are one size thicker. The pin diameter is also roughly the same as for one size larger RS Roller Chain.
