Universal Joints are flexible mechanical connectors. They are used to transmit rotary motion from one shaft to another shaft that is not in line with the first, or when alignment varies. There are two types of universal joints. This is specified by their number of bending joints.
The first type of Universal Joint has one bending aspect. As a result of this, it is capable of operating up to a 45º angle but no more. This is where the double joint style varies.
The second type is the double joint style. This has two bending joints; the double u-joint can operate up to 90º angles.
Steel is the most common material used, either in stainless form; or alloyed with other metals to handle greater torque and temperature. Plastics and thermoplastics are also used in constructing universal joints, as this has greater corrosion and rust resistance. It also has electrical and magnetic insulation in applications.
These joints can also be known as a UJ, universal coupling, and U-joint.
