J80 & J100 Series Joints – Industrial Grade Robotic Joints for Large Robots
DEEP Robotics' J80 & J100 Joint Series are high-generation joint actuators designed for large-scale robotics needs—such as industrial quadruped and humanoid robots—with ultra-high torque, exceptional torque density, industrial-grade environmental protection (IP67) and EtherCAT communication control system.
Variants of the J80 (e.g. J80-27P) and J100 (e.g. J100-64P, J100-116P) have been proven for use in industrial robots such as the X30 model from DEEP Robotics.
Featured Features
- Ultra High Torque & Ultimate Torque/Engineering Ratio
Example: The J100-116P achieves a maximum torque of up to 315 Nm with a torque density of up to 107.5 Nm/kg. - Industry Standards & Environmental Protection
Designed to robotics industry standards, with an IP67 protection rating that allows for use in outdoor and extreme environments. - Multi-turn Absolute Encoder & EtherCAT Communication
Equipped with a multi-turn (high resolution) absolute encoder and EtherCAT support that allows coordination of up to dozens of joints in large robotic systems. - Modular & Compatible with Industrial Drivers
The product supports separate drive-control design, compatibility with industrial drivers, easy integration into existing systems. - Proven in Large Scale Applications
Already used in large industrial robots and humanoids from DEEP Robotics — so its quality and performance are field-tested.
