Where it fits in the robot
NSK describes more than 20 years supplying bearings to robot OEMs, including wave bearings for strain-wave gears and precision motion components.
What the evidence establishes
Robotics productsNSK documents robot bearings, including wave bearings for strain-wave reducers. Bearings support the gearbox; they are not its toothed gears.
A documented robotics component or industrial robot application. Humanoid adoption is not established by the cited source.

Keep in perspective
Bearings span many markets. Robot expertise is established, but humanoid-specific leadership is not quantified.
Diversified business exposure. This describes the breadth or role of the business; it is not an investment rating. A robotics product or development announcement does not by itself establish material humanoid revenue, market share, or future returns.
Connections to the assembly
These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.
Output bearing
Rolling elements support radial and axial joint loads while keeping the output aligned.
Scope of the company links: Bearing suppliers supporting rotating joints. Exact bearing type and fit depend on the robot and gearbox design.
Outer bearing race
The outer race locates the bearing in its housing and provides one of the rolling-contact surfaces.
Scope of the company links: Complete bearing manufacturers; their products incorporate races. This is not a list of independent race-ring subcontractors.
Rolling elements & cage
Rolling elements carry loads with low friction; a cage maintains their spacing.
Scope of the company links: Rolling-bearing products integrate rolling elements and cages. Designs may use balls, rollers, or crossed rollers.
Inner race & shaft interface
The inner ring interfaces with a shaft or moving link. Stiffness and precision affect how accurately a robot holds position.
Scope of the company links: Bearing manufacturers with robot-relevant products; a specific inner-race supply agreement is not asserted.
