BL Series Leaf Chain

A comprises a series of interlocking rings shaped like leaves. Leaf chains are commonly used in applications requiring high tensile strength and low weight. They are widely used in the automotive and aerospace industries, mining, and construction.

Leaf chains are made of various materials, including steel, aluminum, and titanium. The material of the chain depends on the application in which it will be used. For example, steel chains are typically used for high-stress applications, while aluminum chains are used for applications where weight is the primary concern.

BL Series Leaf Chain Sizes:

The BL series has pin and connector plate sizes according to ANSI standards. However, plate size and pin diameter are the next maximum size. This provides greater bearing area and tensile strength, longer wear life and reduced external size. Manufactured according to DIN 8152 Heavy American series. Binding options include 2X3, 3X4, 4X6, 2X2, 4X4, 6X6 and 8X8.

The Structure of the Leaf Chain:

The leaf chain consists of the chain plate and the pin shaft. A pin connects the chain plate to withstand the pull of the chain plate. The outer chain plate has an interference fit with the pin shaft, and the inner chain plate has a sliding fit with the pin shaft. Leaf chains have a greater strength/weight ratio than roller chains.

  1. Outer chain plate

The outer chain plate of the leaf chain is made of special steel, which can resist sudden load and provide maximum resistance to fracture.

  1. Bearing pin

The load-bearing pin of the Elephant and SFR brands leaf chain has strong bending resistance, excellent wear performance, and long life.

  1. Inner chain plate

The precise control of the pin shaft and the aperture of the chain plate improves the movement of the inner chain plate, minimizes friction, and improves the economy and efficiency of chain operation.

Different Types Of Leaf Chains:

  • Open leaf chains the most common leaf chain. They consist of a series of interlocking connections and are shaped like leaves. Open blade chains are commonly used in applications requiring high tensile strength and low weight.
  • Closed leaf chains are a leaf chain having interchained ends that are closed. Closed leaf chains are commonly used in applications requiring high tensile strength and durability.
  • Hinged leaf chains are a type of leaf chain having interchained ends hinged. Hinged leaf chains are commonly used in applications requiring high tensile strength and flexibility.
  • Rubber-coated leaf chains are a type of leaf chain that has the links coated with rubber. Rubber-coated leaf chains are typically used in applications where corrosion resistance is required.
