Humanoid Robot Bearings – Powering the Next Industrial Revolution
Humanoid robots represent one of the most transformative industrial opportunities of the coming decade—and bearings are at the very center of this revolution.
According to Tesla‘s published design drawings for humanoid robots, the rotational and linear drive joints are expected to significantly increase bearing demand. A single humanoid robot may require 70 or more bearings across its joints: crossed roller bearings for rotating joints, four-point contact ball bearings and deep groove ball bearings for linear joints, flexible bearings and crossed roller bearings for harmonic reducers, and various bearings for planetary reducers, RV reducers, and hollow cup motors.
Ouna Bearing‘s Robotics-Ready Product Line
At Luoyang Ouna Bearing, we have been investing in the robotics bearing space for years. Our product lineup includes:
Thin-walled crossed roller bearings – Essential for high-load rotational joints in robot arms, waists, shoulders, elbows, and harmonic reducer outputs. These bearings feature intersecting roller arrangements that provide high rotational accuracy while withstanding radial forces, bidirectional axial forces, and overturning moments.
Harmonic reducer dedicated bearings – Critical for compact, high-ratio drive systems. Each harmonic reducer uses one crossed roller bearing and one flexible bearing.
Bearings for humanoid robots – Custom-designed for emerging robotics applications requiring ultra-thin sections (wall thickness ≤5mm), high rigidity, low friction, and long life (design life >10,000 hours).
High-precision rotary table bearings – For waist and base rotation applications.
Precision four-point contact ball bearings – For linear joints requiring precise axial load control.
Customization – Our Core Strength
Most bearings used in humanoid robots are non-standard structures requiring customized design. Unlike large bearing groups that often decline small‑batch custom orders, Ouna Bearing embraces them. We work directly with your engineering team to develop solutions tailored to your specific joint dimensions, load requirements, and performance targets.
Looking Ahead
As humanoid robots move from demonstration to scaled deployment, reliable bearing supply will be a key success factor. Our products are already used by customers in industrial robotics across Europe, America, and Southeast Asia. We are ready to be your trusted partner in this exciting journey.
