    Shaft Coupling

    Shaft coupling refers to the connection of two shafts or shafts and rotary parts, in the transfer of motion and power process together, under normal circumstances does not take off a device. Sometimes also used as a safety device to prevent the connected parts from bearing too much load, play the role of overload protection.

    Shaft coupling can be divided into two types, flexible coupling and rigid coupling, ATO sells diaphragm coupling and rigid coupling at a favorable price, a variety of sizes to choose from.
