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.
