A universal joint (U-joint) is a mechanical coupling connecting two shafts, enabling them to rotate in different directions while transmitting torque. Comprising two yokes and a cross-shaped member, it accommodates angular misalignment through its flexible design. Primarily used in automotive drivetrains, industrial machinery, and agricultural equipment, U-joints excel in scenarios requiring torque transmission and flexibility. In vehicles, they feature prominently in propeller shafts, steering systems, and marine applications. Industrial machinery benefits from U-joints in conveying and manufacturing systems. Their ability to smoothly transmit power despite misalignments makes them essential components in various mechanical systems, providing versatility in power transmission while accommodating angular variations between connected components.
