    Tips: What is a rotary joint?

    A rotary joint is also called rotary union. It is a closed rotary connector for 360° rotating conveying medium. A 1-passage rotary joint has 1 intake and 1 exhaust. The rotary joint input fluid medium from a stationary pipe into a rotating or reciprocating device and then discharge the medium from the rotary joint. The application fields cover almost every processing and manufacturing industry. For example, metallurgy, machine tool, power generation, oil, rubber plastic, textile, printing and dyeing, pharmaceutical, cigarette, papermaking, food, feed processing, etc.
