ROTARY JOINTS

Rotary joint also known as rotating joint, rotary union, swivel joint etc. are a system of dynamical sealings. The rotary joint is a mechanical device that allows transfer of working medium from a stationary source (stationary supply pipe) to a rotating machinery (cylinder, drum, roll or spindle) for cooling, heating or transfer of fluid power.

A rotary joint is a fluid dynamic sealing device that transfers fluid medium from a fixed pipeline to a pipeline or equipment that rotates or swings at an angle.  The sealing principle is diverse. For example, spherical sealing relies on the axial displacement of the housing driven by a spring to compensate for the wear of the sealing graphite, thus achieving the sealing and isolation of the medium from the outside. [2] In addition, there are various sealing forms such as planar sealing, cylindrical elastomer sealing, labyrinth sealing,  and so on

Rotary joint are used in the following industries: steel industry, paper industry, rubber industry, textile industry, plastic industry, food and medical industry, converting industry and printing industry.
