Product advantages
Focusing on the research and development of the robotic joints, the RJS joint modules has the characteristics
of high positioning accuracy and reliable performance.
- Modular design
- The RJS joint modules integrate motor, driver, harmonic reducer, encoder, and brake. The structure is small and compact. The minimum robot weight consisting of a 6-axis RJS joint module is only 15kg.
- Easy installation
- The RJS joint module simplifies the assembly process of the robot. The assembly process no longer involves complicated parts of assembly and wiring. A 6-axis robot can be completed quickly in only 2-3h.
- Convenient
- The RJS joint module can help you save a lot of time and manpower required in the process of robot design, component selection, performance testing, etc., and provide you with a one-stop solution for robots.
- Safe and smooth
- The RJS joint modules feeds back various position, speed, current, torque, and other various information to the control system in real-time, which is convenient for you to control the robot more safely and make your robot run more smoothly.
- Cost-effective
- We always provide you with high-quality products and services, which gives us an excellent reputation in the industry, and you can get top-quality products at affordable prices.
- Precise positioning
- The RJS joint modules have good positioning accuracy. The repeated positioning accuracy of the 6-axis robotic end using the RJS joint modules reaches 0.02mm, which is suitable for more high-precision industries.
- Strong output
- The RJS joint modules runs powerfully at low speed is quiet and stable at high speed, and can output smoothly under extreme load conditions. The maximum continuous output torque reaches 450Nm.
