Universal Joint Cross

A Universal Joint Cross, or U-joint, is a mechanical device used to transfer rotary motion between two shafts that are not in line. It consists of a central cross-shaped component, with four arms that connect to bearings housed in yokes. These yokes are attached to the shafts, allowing for movement in multiple directions. The U-joint accommodates angular misalignments and allows the shafts to rotate freely, even when positioned at an angle. Widely used in automotive drive shafts, industrial machinery, and agricultural equipment, U-joints are essential for smooth torque transmission in systems where perfect alignment isn't possible. Proper lubrication and maintenance ensure durability and efficient performance.
