Rotary Joint

Rotary joint is also know as rotary union, is a type of rotary seal that connects rotary equipment to fixed pipes and is used to transport steam, water, heat transfer oil, coolant, hydraulic oil, air and other media. Rotary unions can be designed with multiple channels and can manage multiple media types simultaneously. In these cases, the use of a soft seal (such as an O-ring) prevents the fluid from “crossing” into another channel. Soft-sealed multi-channel rotary unions are widely used in a variety of industries and applications, including oil and gas, food and beverage, aerospace, robotics and medical equipment. In some applications, rotary joints are equipped with slip rings for transmitting electrical signals and hydraulic power.

Thanks to the slip ring manufacturing business, GRAND technology start from pneumatic/hydraulic rotary joints with electrical slip rings. Now we have developed multi-channel rotary joints, pneumatic rotary joints, hydraulic rotary joints and wind generators hydraulic rotary joints. Can provide one-stop solution for rotary transmission application.
