Engineering Chain

Strong load-bearing capacity: Engineered chains have high strength and durability, capable of withstanding the weight load of heavy machinery and equipment.

In countless industrial scenarios, engineering chains are a silent but powerful force. It carries important tasks, transmits power and kinetic energy, and connects various mechanical devices, equipment and processes. Just as blood flows in the human body, engineering chains flow in industry and inject vitality and efficiency into production lines in various industries. is not just a part of machinery, it represents the precision of modern industry and the progress of technology. Let's delve deeper into the importance and wide range of applications of engineering chains.


In the engineering industry, chains are used in conveyor systems and drive systems. They are made with pin joints and links that provide strength and rigidity. They are also able to move sideways and go around curves. These types of chains have been around since the 1880s. They are made from hot-rolled steel and are sometimes heat-treated for added strength. They are used in conveyors, bucket elevators, and oil drilling machines. They must be able to withstand the power produced by the prime mover.

Engineering Chain Features

The engineering chain is a measuring tool to measure distances accurately. It is comprised of links that are connected at right angles. Typically, the chain length is five, ten, twenty, or thirty meters. Links are spaced one foot apart, and each link measures 7.92 inches. These chains are also equipped with brass rings or tallies that mark one metre intervals. This makes it easier to determine the total length.

There are two types of engineering steel chains: those designed for lifting and those designed for conveying. A lifting chain needs to be capable of withstanding high tensile stresses, and it must be ductile and resilient enough to withstand fatigue. Most engineering steel chains are used in conveyor applications, while others are used in drives. You can find engineering steel chains in conveyors, forklifts, bucket elevators, oil drilling machines, and more. These chains must be able to withstand the power generated by the prime mover.

Roller Chains VS Engineering Chains

In general, engineered chains are somewhat distinct from roller chains. Roller chains are generally utilized for power transmission, while engineered chains are utilized for handling materials. There are some differences in structure between the two kinds of chains, which is why it is essential to make sure that you choose the right chain to meet your needs. Rollers are not typically required in material handling chains, however, they are an essential component of the power transmission chain. If you're using roller chains, you can expect high-speed operation is more secure, and engineered chains are more robust, durable and last longer because they have a smaller distance between the sprockets.

Roller Chain Applications in Heavy Machinery

Roller chains consist of a series of interconnected links, including inner links, outer links, and roller pins. The inner links and outer links alternate with each other and are held together by the roller pins. The rollers are located between the inner and outer links and rotate freely on the roller pins. This structure allows the roller chain to transmit power and motion efficiently.

The working principle of a roller chain involves the engagement of the rollers with the teeth of the sprockets. As the driving sprocket rotates, it pulls the chain, causing the rollers to engage with the teeth of the driving sprocket. This engagement transfers power and allows motion to be transmitted from the driving sprocket to the driven sprocket.

Double row chain

Double-row chains consist of two parallel rows of interconnected links, which provide higher load-carrying capacity and increased transmission power compared to single-row chains. The structure of double-row chains allows for more contact points with the sprockets, enhancing stability and precision in power transmission.

Double-row chains find application in various fields, including:

Conveying Equipment: Double-row chains are commonly used in conveyor systems for material handling. They provide efficient and reliable power transmission, making them suitable for heavy-duty applications in industries such as mining, automotive, and logistics.
