RJSII series joint modules for industrial applications

The RJSII series joint modules are the second generation of RJS joint modules launched by Techservo to solve the needs of industrial robots, medical, military, aerospace, and other applications.

Explore and innovate security cooperation

• The new design structure has better heat dissipation performance and can be applied to the working scene of -20 ℃ -50 ℃
• The output is more powerful and the average load torque is larger, which can be used in the robotic 15-20kg payload
• With better waterproof and dustproof performance, protection grade IP54 (IP64 optional), suitable for more demanding industrial environments

RJSII series joint modules

Seiko quality, originality

Solve the adaptability and stability of robots in more complex work environments

Repeated positioning is more accurate
Double encoder feedback for precise position control
Traditional friction brake
Friction brake, short braking time, better braking effect, and safer.
Industrial grade protection
With better waterproof and dustproof performance, protection class IP54 (IP65 optional)
New custom motor
Using a new custom motor, the rated load speed of the motor is increased by 15%
Optional communication
Support EtherCAT, CANopen communication optional
New design
New design, smaller size and lighter size
