This joint adopts a bearing structure and features Dublin’s proprietary “disengagement” design. Its unique elastic diaphragm allows it to “disengage” the sealing surface when there is no cooling pressure, and then return to the closed state after pressure is restored.
Performance characteristics:
Single channel, coolant or MQL;
Detaching M technology can achieve unrestricted dry operation without mass pressure;
Full flow design, no debris or burr blockage;
Bearing support and threaded rotor, easy to install;
Double ABEC7 (ISOP4 grade) angular contact ball bearings;
Adopting labyrinth seal and large leakage port to protect ball bearings;
Balanced mechanical seal, made of silicon carbide material, can extend its service life even under harsh working conditions;
Anti corrosion anodized aluminum shell.
A rotary joint is a sealing device that connects stationary pipelines and rotating equipment, achieving leak free fluid transmission under 360 ° rotation. It allows fluid media to flow smoothly between fixed pipelines and rotating machines, and is a key component in industrial equipment

JD40 rotary joint is a key sealing component in industrial fluid transmission systems, usually referring to a rotary connection device with a diameter of DN40 (or corresponding British caliber). As a transitional sealing device that transports fluid media (such as water, steam, hydraulic oil, thermal oil, compressed air, etc.) from static pipelines to dynamic rotating or swinging equipment
