Ceramic Components for Humanoid Robots

We specialize in precision ceramic components for humanoid robots and intelligent hardware. Our custom structural parts include joint shafts (shoulder, elbow, wrist, knee), ceramic balls, insulating rings, vacuum chucks, fingers and shafts. Backed by full in-house R&D and precision machining, we effectively eliminate joint wear and EMI challenges. We also support collaborative engineering tailored to your operational needs. We welcome custom manufacturing based on your drawings, providing full support from rapid prototyping to scalable mass production.

  • Size:Customized on demand
  • Customize:Can be customized and reverse developed according to drawings and samples.

    Performance characteristics

    Our ceramic components are engineered to maximize robot performance, especially across high-stress joints and drivetrains. Combining good wear resistance with minimal thermal expansion, they maintain critical dimensional accuracy and repeat positioning through continuous high-frequency motion. Significantly lighter than conventional metals, they cut dynamic robot weight while providing total electrical insulation to eliminate current leakage and motor EMI. With good resistance to heat and corrosion, our parts deliver the lightweight durability and precision consistency essential for stable, long-term robotic operation.

    Application Areas

    Humanoid Robots

    Humanoid Robots

    In humanoid robotics, Companion ceramic components are widely used in joint transmission, sensing systems, and end effectors. Alumina, zirconia, silicon nitride, and silicon carbide offer high hardness, low density, and excellent insulation—helping reduce joint wear, cut weight, and minimize electromagnetic interference. Products include ceramic fingers, balls, chucks, and insulating rings/gaskets, with one-stop support from material selection and prototyping to large-scale delivery.
