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.","assessed_in":{"domain":"Humanoids","list":"Humanoids 100","rank":14,"score":83,"tier":"member","scores":{"gate_ne":["technology","firepower"],"leverage":8,"position":8,"progress":10,"firepower":10,"commercial":10,"deployment":6,"production":8,"technology":8},"why":"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.","segment":"Actuation","layer":"Components"},"signals_total":17,"facts_total":14}],"note":"Assessment by Frontier Tech Intelligence; facts and signals carry their sources."}
