NSK Ltd. was, according to Wikipedia, founded on November 8, 1916 in Tokyo and is headquartered in Shinagawa-ku, Tokyo. NSK is Japan's largest bearing manufacturer and makes industrial and automotive bearings, precision machinery and components. The company is listed on the Tokyo Stock Exchange under the code 6471 (ISIN JP3720800006) and is a component of the Nikkei 225.
Component and function
Alongside bearings, NSK supplies linear-motion technology: ball screws and linear guides for precise motion control. These precision components convert rotation into accurate linear motion or guide moving assemblies with low friction — core functions in machine tools, semiconductor manufacturing, handling systems and the axes of robots. NSK thus covers both the bearing and the linear-motion side of precision drives.
Role in the value chain
NSK is a specialized component supplier and does not build complete robots. Its combination of rolling-bearing and linear-motion expertise makes it a standard supplier to precision machine building and the automotive industry. NSK produces about three million bearings per day by its own account.
Key figures
For fiscal year 2026 stockanalysis.com reports revenue of about ¥911.64 billion (up 14.43% year-on-year) with net income of roughly ¥22.87 billion. Market capitalization stood at roughly ¥550.73 billion according to stockanalysis.com; the company employs about 26,278 people.
Market position
NSK is among the world's leading bearing makers and at the same time an established supplier of ball screws and linear guides. Its business is cyclical and follows the cycles of the automotive and manufacturing industries.
Robotics as a growth field
As automation increases, demand grows for precise linear axes and bearings. As Japan's largest bearing maker at the same time, NSK can combine bearing and linear-motion expertise — an edge over pure linear-motion specialists, offset by the price dynamics of the global bearing industry.
Opportunities and risks
NSK combines rolling-bearing with linear-motion expertise and is thus anchored in automotive as well as industrial and robotics value chains. Its recent revenue and profit growth was, per the company, driven by structural reforms and favorable exchange rates. Opportunities arise from e-mobility, factory automation and growing demand for precise ball screws and linear guides. Risks lie in heavy dependence on the cyclical automotive and industrial business, global price competition in the bearing industry and currency effects. As a supplier of key components, NSK must pool its bearing and ball-screw manufacturing know-how and continually tune its globally distributed production for cost and quality. For investors, NSK is thus an established industrial play that combines bearing and linear-motion technology and is driven by both the automotive and automation cycles.
