Universal joint can be divided in many different types which used is different machines to have different functions. It is really difficult for the user who want to choose a suitable universal joint but have no thoughts about how to choose universal joint.
A universal joint is a mechanical device that allows one or more rotating shafts to be linked together, allowing the transmission of torque or rotary motion. Universal joint also allows for transmission of power between two points that are not in line with each other. Universal joints come in a wide variety of shapes, sizes and configurations to accommodate the infinite types of applications. You should always consult a professional before selecting a universal joint.
Why are universal couplings widely used? Universal couplings are just like the joints of human hands and legs, and the structure of the machine is different from humans. They have different functions and different forms. Therefore, the universal couplings used on the machine are far more than ours.
