    • 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 28mm 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 are the benefits of chain coupling?

    Chain coupling is a design pattern in software engineering where multiple components in a system are connected through a sequence of function calls.  Each component in the chain passes information to the next component, which then performs some processing and passes the information on to the next component, and so on.

    One of the benefits of chain coupling is that it promotes loose coupling between components, which makes the system more modular and easier to maintain.  Loose coupling means that each component in the chain only knows about the component immediately before and after it, rather than having direct knowledge of all the other components in the system. This reduces the dependencies between components, which makes it easier to modify or replace one
    component without affecting the others.

    Another benefit of chain coupling is that it allows for easy customization and extension of the system. New components can be added to the chain without modifying the existing components, as long as they follow the same interface and data format. This makes it possible to add new functionality to the system without disrupting the existing functionality.

    Finally, chain coupling can improve the readability and understandability of the code, as each component in the chain performs a specific task and the flow of data is easy to follow. This can make it easier for developers to maintain and debug the code, as well as for new developers to understand the
