Universal Joint or Universal Coupling

A universal joint, also known as a U-joint, is a mechanical device that allows for the transmission of rotary motion and torque between two shafts that are not in line with each other. It consists of two yokes connected by a cross-shaped component called a spider. This design enables the joint to accommodate angular misalignments and changes in alignment while maintaining smooth motion. Universal joints are commonly used in automotive applications, such as in driveshafts, as well as in various machinery and equipment where flexibility in movement is required, making them essential for efficient power transfer in non-linear configurations.
