A WSS Telescopic Universal Coupling is a mechanical power transmission device designed to transmit torque between two shafts that may be misaligned while also accommodating axial movement (length variation). It combines the functions of a universal joint and a telescopic shaft, making it ideal for applications where both angular misalignment and shaft extension or contraction are present.
This type of coupling is widely used in rolling mills, cranes, heavy machinery, automotive systems, and industrial drive lines.
