Humanoid actuators

Humanoid picks-and-shovels — the component layer holds value only where China compression fails (roller screws, novel-process motors, the sovereignty channel)

The callHumanoid actuators are half the bill of materials, but Chinese capacity, incumbent supply deals and startups priced as winners closed the window in mid-2026.

Fig. 1The balance. Drivers and catalysts against restraints, each block sized by its weight; catalysts hang dashed because they have not happened yet, sized by their odds. It tips toward the restraints.
  1. D1Humanoids become a mass product, and actuators are about half the bill of materials; Optimus's 14 roller screws alone are about 19% of its cost.
  2. D2Today's parts were built for industrial arms and aircraft in small volumes, and the motors rely on rare earths China put under export control in April 2025.
  3. D3Process ideas like Alva's fibre-printed stators could make a joint by the million without Chinese rare earths.
  4. R1Chinese roller-screw capacity arrived: Beite at 2.6M sets a year, Beite and Wuzhou already in the Optimus chain.
  5. R2The incumbents responded: Schaeffler's 5-year supply contract for over half a buyer's needs and a humanoid actuator line at CES 2026.
  6. R3The startups are past early prices (Alva €16M, Humanoid $152M), and Harmonic Drive, Nabtesco's unit and maxon together did about $1.6B in 2025 after decades.
  7. C1Tesla's Optimus line in Fremont starts production, a buyer of 1M a year that needs non-Chinese actuator supply.2026
  8. C2A Chinese roller-screw maker wins a Western OEM socket at volume, or a Western startup gets into the layer.31 Mar 2027

What changedthe record, newest first
  • 7 Aug 2026In humanoids the money is going to the robots, not their parts: platforms raised billions this year while actuator components drew two deals. The parts layer is being locked up by one German tier-1 and squeezed by Chinese capacity, and the few component startups that proved their process have already raised past entry size.
  • 4 Jul 2026The picks-and-shovels instinct on humanoids needs narrowing: China has already compressed the shovel price in gears (a third of the Japanese incumbent's price), motors and robot hands (one Shenzhen vendor ships 80% of the world's high-dexterity hands). What resists is the unglamorous precision layer, planetary roller screws are still a Swiss duopoly and a fifth of Optimus's cost, and manufacturing-process moats, where Samsung and the world's biggest gear incumbent just backed a Norwegian motor startup. The Apr 2025 rare-earth squeeze on Optimus gave every Western OEM a reason to pay for non-Chinese supply.
