    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.

    Do you have suitable slip ring?
    Do you have any model of your slip ring that fit the size of the attached drawing (all numbers in mm)? The slip ring needs to fit 1 fiber optic and 24 coaxial cables.

    ATO Responded
    Unfortunately, our slip rings cannot fit 1 fiber optic and 24 coaxial cables. These two signal lines can only be used separately.
    Slip ring runs well
    It feels like the slip ring is well made, frictionless and comes with thick, high quality wire. Used to connect underwater camera with cable reel to monitor, the reel turns the monitor without rotating the ring very well, which is a good choice.
