Product Description

The planetary roller screw is integrated into the actuation system of humanoid robot joints—such as the hip, knee, shoulder and elbow—as a core transmission component. Its primary function is to convert the motor’s rotary motion into highly precise and rigid linear or rotary output, enabling accurate control of the joint’s position and velocity. The planetary roller screw addresses these challenges through its multi-roller parallel architecture, delivering high stiffness and load capacity within a compact footprint. Its low-friction, high-precision design ensures smooth gait transitions and accurate motion execution, whilst its excellent fatigue resistance guarantees consistent positioning accuracy over extended operation—effectively resolving critical trade-offs in integration density, control fidelity, and reliability for humanoid robot joints.

Company Profile

Schaeffler Embodied Intelligence Robotics (Taicang) Co., Ltd.

Founded in 1946 and headquartered in Bavaria, Germany, the Schaeffler Group is a technology company specialising in drive technology, with three major product brands: INA, LuK and FAG. Focusing on four key areas – electric drive, low-carbon drive, chassis applications and renewable energy – Schaeffler offers a comprehensive range of products and services related to drive technology through its eight product families. Having invested in production in China since 1995, Schaeffler has, for over 30 years, adhered to the principle of “serving the local market with local resources”, deeply engaging in local production and R&D to provide customers with high-quality products and localised services. Schaeffler Embodied Intelligence Robotics (Taicang) Co., Ltd. is a wholly-owned subsidiary established by Schaeffler in China. Located in the Taicang High-Tech Zone, the company specialises in the R&D and production of core components and key subsystems for humanoid robots, whilst also providing value-added services such as training, iteration and data sharing. The company has established a comprehensive R&D and manufacturing system, encompassing facilities such as an intelligent R&D centre. By integrating humanoid robotics with smart manufacturing systems, it has created a novel production model. Furthermore, by combining cutting-edge technologies such as smart manufacturing and digital twins, and adopting a three-pronged approach of “cutting-edge R&D + implementation of smart factories + accumulation of data assets”, the company is driving business growth. Leveraging a comprehensive portfolio of drive technology products, Schaeffler Embodied Intelligence Robotics provides a wide range of products for humanoid robots, including rolling bearings, roller screws, precision gearboxes, motors, sensors, linear and rotary actuators, as well as thermal management and battery management modules, meeting the functional requirements of humanoid robots in areas such as drive systems, transmission, perception and feedback, power control, and energy management.
