    • Chain shaft coupling provides direct power transmission between two components without any slip or play, which contributes to efficient power transmission and reduced energy loss.
    • 12 to 16mm chain coupling can accommodate a certain degree of misalignment between the shafts of the two components it connects.
    • Chain couplings are designed to absorb shock loads and vibrations that may occur during operation, which helps to protect the components and extend their life.
    • The roller chain coupling has a simple structure and is easy to install and disassemble, without moving the two coupled shafts.

    Chain coupling dimension


    Chain couplings are commonly used in industrial applications where there is a need to transmit power between two rotating shafts. They are known for their high torque capacity and durability, and are often used in applications where there are large axial and radial misalignments between the shafts. Chain coupling is widely used in various industries, including automotive, aerospace, and manufacturing.

    Tips: What is chain coupling?

    A chain coupling is a type of mechanical coupling used to connect two shafts together in order to transmit torque and rotational motion. It consists of two sprockets or gears connected by a chain, with each sprocket mounted on a shaft. The teeth of the sprockets mesh with the links of the chain, allowing the torque to be transmitted from one shaft to the other.

    Chain couplings are commonly used in applications where the two shafts are not perfectly aligned, as the chain can compensate for some misalignment. They are also useful in applications where shock loads or vibrations are present, as the chain can absorb some of the shock and prevent damage to the shafts or other components. However, chain couplings are not as precise as some other types of couplings, and they can produce more noise and vibration than other options.
