Leaderdrive supplies harmonic drives to an estimated 60%–70% of humanoid manufacturers and is forming a China-based venture with SKF for humanoid robot transmission components.
Darker bar: ahead of the other company on that measure.
Leaderdrive is China's harmonic-reducer volume leader (STAR-listed) with 2025 revenue of RMB 570.7M (~$79M, +47%) and net profit of RMB 124.4M (more than doubled), pricing aggressively against Harmonic Drive Systems. It is the price-disruption side of the reducer duopoly-in-formation, with capacity of 790,000 reducers a year (plus a new project adding 1M more), a 30-40% Chinese harmonic share per J.P. Morgan, and customers across the Agibot, UBTech, and Tesla Optimus supply chains. Its industrial and humanoid joint demand is the driver.

NSK is contributing its precision-parts technology to the joint development and testing of humanoid robot components with Atom, including components relevant to robotic motion and actuation.
Darker bar: ahead of the other company on that measure.
NSK is a Japanese bearing and actuation maker (TSE:6471) that established a Robotics Business Division in March 2026 and announced miniaturized rotary and linear actuators for humanoids, plus a February 2026 design win supplying a third-generation smart joint bearing module (with integrated torque and temperature sensing) to a leading North American humanoid robot company. Its agreed merger with NTN will create the world's largest bearing maker (~$11.1B combined revenue, closing 2027), with both companies naming physical-AI robots as the priority battleground, and it signed a Delta Electronics MOU (May 2026) for joint actuator modules. With more than 70 bearings per humanoid, this is a components-scale play against JTEKT, SKF, and IKO.
