Universal joint is a kind of coupling of mechanical transmission parts. It can be said that universal joint belongs to coupling. There are many kinds of coupling, such as plum blossom coupling, expansion sleeve coupling, elastic coupling, parallel coupling, diaphragm coupling, universal coupling and so on. They are all couplings with different types and different selection and use conditions.

Universal joints are also called universal couplings. Universal couplings are mostly used in situations with large torque and poor concentricity of two axes.

Friends who are interested in universal coupling are welcome to call for consultation or negotiation.
