1109-023-212 deep hole drilling high-speed rotary joint

Core application scenario: Deep hole drilling (gun drilling, BTA drilling, etc.) with cooling fluid inside the spindle, achieving leak free liquid supply under high pressure (usually ≤ 1.0 MPa) and high speed (≤ 3000 rpm), ensuring chip removal and tool cooling.
Typical equipment: machining center, dedicated deep hole drilling machine, CNC boring and milling composite machine tool, automated drilling unit.
Medium type: water-based coolant, cutting oil, micro lubricating (MQL) fluid, or low-pressure compressed air (depending on the specific sealing configuration).

Structural features: The 1109 series is a bore mount center outlet joint that uses balanced mechanical seals and high-precision bearing support. It is compatible with the hollow spindle end and supports radial or axial flow channels (1109-023-212 is usually an M16 × 1.5 threaded interface). ‌‌
Structural features: Made of corrosion-resistant materials, specially designed to operate under limited conditions without damaging the joints, the sealed rolling bearings do not require lubrication for life, and the balanced sealing load and wear are reduced to the limit, reducing torque. The sealing material has self-lubricating properties, and the spring component is located on the outside of the fluid channel, which can reduce pressure loss and avoid particle retention in the medium. Overall, it improves the quality of the fluid and is suitable for water, hot oil, and steam applications. The flexible stainless steel outer tube is corrosion-resistant, with a longer service life and a complete and uniform flow design. The pressure loss is small, and two precision imported bearing supports ensure long-term fault free operation. The balanced mechanical seal design reduces the wear of the sealing surface caused by the sealing load, greatly extending the service life.
