Universal Joint

A universal joint, also known as a U-joint, is a mechanical coupling used to transmit torque and rotational motion between two shafts that are not aligned with each other. It is commonly used in automotive and industrial applications where the connected shafts need to accommodate angular misalignment. The universal joint consists of a cross-shaped piece of metal with bearings at each end. The cross is typically made of steel or another durable material. The bearings allow the cross to rotate freely and transmit torque between the connected shafts. The cross is usually located inside a housing or yoke, which provides support and protection.
