Rotary joint to prevent twisting and interference of the rotating part's tube.
Preventing air tube troubles! A slim rotary joint that enables infinite rotation of pneumatic equipment.
The "Rotary Joint" is a piping fitting that allows pneumatic equipment to rotate infinitely without interrupting the pneumatic circuit. It is designed to be 50-60% thinner in height compared to conventional products, minimizing the load on robots. Additionally, it eliminates interference and twisting of air tubes, preventing troubles in advance and making it easy to pipe for robots. It is widely used in FA equipment that flips and rotates workpieces in applications such as cylindrical surface inspection, material handling within machine tools, and the automotive industry. We also have case studies available, so please take a look. 【Features】 - Prevents piping interference by being installed at the robot's end effector - 50-60% thinner in height compared to conventional products - Easy piping for robot air tubes! - Easy positioning and wiring with precision holes that penetrate the product! - IP65 equivalent dustproof and waterproof specifications are available *For more details, please refer to the PDF document. We also offer sample loans, so feel free to contact us.
