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.
