Through hole hydraulic rotary joint
Through hole hydraulic rotary joint, center through-hole design, 360 ° continuous rotation, multiple path options, stainless steel material, high-pressure sealing without leakage, can transport hydraulic oil, cooling water, compressed air, suitable for machine tool fixtures, rotary workbenches, and automated turntables, supporting non-standard customization
The through‑hole hydraulic rotary joint (also called hollow shaft rotary union) adopts a central through‑bore structure. It allows shafts, cables, pipelines to pass directly through the center while realizing 360° unlimited relative rotation between stationary and rotating parts. It is widely used to transmit hydraulic oil, cooling water, compressed air and other media, solves the problem of hose twisting and winding during equipment rotation. Stainless steel housing and high‑performance sealing components ensure stable operation under high pressure. Custom passages, bore diameters and flange interfaces are available for machine tools, rotary tables, automation fixtures and indexing equipment.
Main Features:
- Central through‑hole design：Hollow central bore for passing drive shaft, electric cable or air tube, compact installation space.
- 360° continuous rotation：Unlimited rotation angle, no hose torsion, avoid pipeline breakage.
- Multi‑passage optional：2/3/4/6+ oil/gas passages, can transmit multiple media at the same time.
- High‑precision sealing system：Wear‑resistant seal pairs, low leakage, long service life, low rotating torque.
- Stainless steel housing：Anti‑rust, corrosion resistant, suitable for humid and coolant environment.
- Flange mounting：Standard flange connection, easy installation and alignment.
- 可自定义：Bore size, port thread, number of passages, pressure rating can be customized.
