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.

In modern industrial production, the rotary joint serves as a crucial component for connecting fixed pipelines with rotating equipment, and is responsible for transporting various fluid media. Whether it is a CNC machine, packaging machinery, or heavy engineering equipment, none of them can do without this "joint"-like precision component. When faced with a wide variety of rotary joints on the market, how can you choose the most suitable product for your equipment? This article will guide you to understand the basic classification of rotary joints and focus on introducing the selection key points of multi-path rotary joints.
