Screws & Linear Motion Suppliers for Humanoid Robots
About This Category
Ball screws, planetary roller screws, and linear actuator components that convert rotary motor motion to linear joint displacement. Critical for arm extension, leg actuation, and gripper motion.
Linear motion in robot limbs and grippers depends on precision screw mechanisms. Noted as a key bottleneck by analysts due to tight tolerances and limited high-volume suppliers.

SKF
Planetary roller screws and precision bearings for humanoid robot linear actuation. McKinsey identifies planetary roller screws as presenting the most acute supply chain bottleneck risk in humanoid robotics — a high-precision niche with a narrow supplier base, long lead times, and limited substitution options. SKF is the primary Western-origin supplier of precision roller screws and cross-roller bearings for humanoid robot joint systems.
