NSK ranks 14 on the Humanoids 100 with a score of 83; AAC Technologies ranks 62 with 62. NSK is ahead on deployment, commercials, progress, technology, positioning, firepower and leverage. Level on production. AAC Technologies is based in Shenzhen, China, NSK in Tokyo, Japan. NSK: Established. AAC Technologies is named in 1 signals and NSK in 17.
AAC Technologies, an acoustics and haptics supplier, is applying its precision motors, actuators and miniaturized sensing to robot components.
Darker bar: ahead of the other company on that measure.
AAC Technologies is a Chinese precision micro-motor and haptic-actuator maker (HKEX:2018, from a smartphone base) positioning its miniature-actuation expertise toward robot joints and dexterous-hand micro-joints, plus acoustics for human-robot interaction. Its relevance is structural (the same basis as Sunny Optical), but no dated humanoid win was found this pass (verified-light). The current group revenue marker is dated.

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.
