1109-011-165 swivel union

The “disengagement” technology can achieve unlimited dry operation without medium pressure.
1109-011-165 is a 1109 series “Breakaway” hole installation type center outlet rotary joint. This series of products is designed specifically for high-speed spindle center water discharge applications and is widely used in deep hole machining, automation control, and high-precision machine tool fields. Its core function is to stably transfer fluid media (such as coolant, air, or MQL trace lubricants) from a relatively stationary pipeline system to high-speed rotating spindle components, while ensuring no leakage, low vibration, and high concentricity.
Full flow design, no debris or burr blockage.
