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.
