Multi‑Passage Rotary Joints – Selection Guide & Brand Overview

In the fields of hydraulic machinery, machining center rotary tables, construction machinery, wind power generation, and other high-end equipment, high-pressure multi-path rotary joints play a crucial role. They need to simultaneously transmit multiple high-pressure media - hydraulic oil to drive the actuators, coolant to remove heat, and compressed air for control - while ensuring no leakage. If the selection is incorrect, it could lead to equipment downtime at the very least, and even cause safety accidents at worst. This article will systematically analyze the selection key points of high-pressure multi-path rotary joints and help you make the right choice.
