Hollow Pin Leaf Chains FL36

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.

Hollow Pin Leaf Chain Features:

Stainless steel hollow pin leaf chains are widely used in the oil and gas industry. Steel needles come in different hardness and thickness, which makes them very durable. These drive chains have strict tolerances and are of perfect quality to withstand the rigors of offshore applications. The stainless steel components of these chains are heat-treated for higher hardness and excellent fatigue resistance. They come in a variety of sizes from single to multiple rows and are soldered to the delivery parts.

This type of chain is a good choice for many different applications. Its simple design makes it easy to install different accessories, commonly used in conveyors. The center distance between the sprocket and the pin remains the same regardless of the length of the chain pitch. The hollow pin chain also does not expand or contract when the chain is bent. The design of the hollow pin leaf chain is user-centered.

Cross bars between the two chains distribute the load evenly, reducing the risk of chain twisting. Hollow pin leaf chains also have a lower maximum allowable tension compared to standard sprockets. Features of our hollow pin leaf chain include durability, low maintenance, and ease of assembly and disassembly. This type of leaf chain is also ideal for heavy duty as its cross rods are made of stainless steel.




We are one of the best leaf chain suppliers. We can offer comprehensive leaf chain stock. We have exported our products to clients worldwide and earned a good reputation because of our superior product quality and after-sales service. We welcome customers at home and abroad to contact us to negotiate business, exchange information, and cooperate with us!

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.
