Product Delivery

Our Advantages
Direct connection can improve reliability and reduce costs. The workbench and robot arm that need to be installed can be directly installed on the rotating platform. Compared with the use of mechanical parts such as pulleys, the time and cost of mechanical design, parts allocation, belt state adjustment and other links can be reduced.
Motor configuration
You can freely choose stepper motors or servo motors of various brands, except for the KTN series dedicated stepper motors.
High-precision positioning without backlash
No backlash, positioning accuracy ≤15sec, and repeated positioning accuracy can reach ±5sec.
Large-diameter hollow structure
Wiring and piping are more convenient and simple, and this feature is particularly prominent in wiring and piping environments with complex wiring.
