This linear actuator is designed for linear joints on humanoid robot limbs. It integrates drive system, transmission structure, force sensing and position feedback as a single unit, equipped with large-lead planetary roller screw, four-point contact bearing, high-performance frameless torque motor, high-precision inductive encoder and high-precision tension force sensor.

High Thrust Density

It provides a maximum thrust of up to 8 kN with compact and lightweight dimensions, meeting the weight reduction demands of humanoid robots.
Dual Full Closed-Loop Sensing

Position and force dual closed-loop control enables precise flexible motion, landing buffering and external force detection.
Highly Integrated Monolithic Structure

The motor, screw, sensors and bearings are entirely encapsulated inside the cylinder, simplifying wiring layout and improving overall assembly efficiency.
Superior Dynamic Response

The combination of frameless torque motor and large-lead screw delivers fast extension and retraction, suited for high-dynamic gaits including walking, running and jumping.
Shock Resistance & Durability

The planetary roller screw paired with heavy-load bearings withstands impact loads from robotic gaits, extending the service life of the whole actuator.

Micro actuators are deployed for joint driving of dexterous robotic fingers.

The servo electric cylinder is a modular unit with integrated servo motor and lead screw assembly. It transforms the rotary output of the servo motor into precise linear displacement, representing a groundbreaking new generation solution for high-accuracy linear motion systems.
