Summary
Nabtesco (TSE: 6268) was established in 2003 through the integration of Teijin Seiki and NABCO and reports three segments: Component Solutions (which includes precision reduction gears), Transport Solutions and Accessibility Solutions. Its RV reducer is a cycloidal gear used in the heavier joints of industrial robot arms; the company’s own estimate is about 60% of the global market for reducers in the joints of medium-to-large industrial robots. FY2025 (ended December 2025) net sales were ¥307.9B. For the first half of FY2026 (IFRS) it reported net sales of ¥167.4B, operating profit of ¥15.8B (+72.4%) and net income of ¥12.4B (+90.6%), and on 2026-07-31 raised its full-year forecast to ¥344.0B of sales. These numbers come from an AI-generated summary of the filings.

What It Is / How It Works
The RV (Rotate Vector) reducer uses an eccentric drive and cycloidal discs to give high torque capacity, rigidity and overload resistance in a compact package. Nabtesco describes it as supporting fast acceleration, smooth motion, low backlash and accurate positioning, and names industrial robots on automobile lines as a main application. It sits in the base, shoulder and elbow joints of industrial arms, complementing strain wave gears from Harmonic Drive Systems in smaller joints.
The July 2026 summary says precision reduction gears were among the drivers of steady demand, without quantifying them; the company’s robot page does not mention humanoid robots.

Supply Chain Position
Nabtesco is a component supplier selling reducers to robot OEMs. ⚑ Shared customer base with Harmonic Drive: both Japanese suppliers serve the same robot makers for different joints. ⚑ Rare earths: the reducers are steel mechanisms; exposure lies in the motors driving them.
