Universal Joint

Universal Joint:
A universal joint, also known as a U-joint, Cardan joint, or Hardy Spicer joint, is a mechanical component used to transmit rotational motion between two shafts that are not in line with each other. It allows for the transmission of power at various angles and can accommodate misalignment between the shafts.

There are several common types of universal joints, including:

Cross-Type Universal Joint: Consists of four arms connected in a cross formation with needle bearings at the pivot points.

Single and Double Cardan Joints: Comprise two yokes connected by a cross piece (single) or two crosses (double) to transmit motion at sharper angles.

Universal joints are essential in automotive drivetrains, industrial machinery, and other applications where flexibility in transmitting rotary motion is necessary. Proper maintenance and lubrication of universal joints are crucial to ensure smooth operation and longevity in mechanical systems.
