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},{"name":"Zhaowei","url":"https://www.frontiertechintelligence.com/companies/zhaowei","city":"Shenzhen","country":"China","stage":"Established","founded":null,"last_round":null,"positioning":"Zhaowei is a Chinese maker of precision gearboxes and micro-drives (SZSE:003021) named in supply-chain trackers as supplying Optimus joints, on an established micro-drive business in consumer electronics and auto.
