What is a hydraulic rotary joint

21 . Jun . 2024

Hydraulic rotary joint is a type of rotary joint specifically designed for low-speed, high-pressure, various media, and multi-channel equipment, serving equipment such as machining center rotary workbenches, hydraulic workstations, coilers, converters, large package rotary workbenches, hydraulic machinery, and multi-channel high-pressure controllers.
Due to the advantages of hydraulic transmission over electrical and mechanical transmission, hydraulic transmission is increasingly used in various industries. The application of hydraulic rotary joints is gradually becoming widespread. If the hydraulic actuator is fixed relative to the medium source, steel pipes can be used to transport the medium to the actuator. If the actuator has a small amount of movement (movement, rotation, oscillation) relative to the medium source, a high-pressure hose can be used for connection. If there is a hydraulic cylinder on a high-speed rotating shaft, a rotary joint is required to transport the medium to it. At present, there is no standardization of rotary joints, and there are relatively few manufacturers.
