Universal Joint (U-joint)

The universal joint (U-joint) is a mechanical coupling that facilitates the transmission of rotary motion between two non-aligned. It comprises two yokes by a central cross or spider mechanism, permitting angular misalignment while sustaining rotational movement. The shafts feature keyways for secure attachment, and the assembly is secured with bolts and pins for durability. Metallic sleeves enhance reinforcement or provide housing for bearings. Universal joints are widely used in automotive drive shafts, industrial machinery, robotics, and aerospace applications.
