Business
NSK Ltd. (NSK) was founded in 1916 as Japan's first bearing manufacturer, boasting a history of over 100 years. The company operates in three segments: Industrial Machinery Business (bearings for general industry, precision equipment, Condition Monitoring Systems), Automotive Business (Hub Unit Bearings, transmission components, etc.), and Steering Business (electric power steering, etc.). With 90 consolidated subsidiaries and 18 affiliated companies, NSK has built a global manufacturing and sales structure spanning the Americas, Europe, China, ASEAN, and other regions. In September 2025, the company made NSK Steering & Control Corporation a wholly owned subsidiary, bringing the Steering Business into consolidation. Major customers span the industrial sector broadly, including automotive and parts manufacturers, and machine tool and semiconductor manufacturing equipment manufacturers.
Business Model
NSK supplies mechanical components such as bearings, ball screws, and linear guides directly to automotive and industrial machinery manufacturers, underpinned by a global mass-production system based in its own factories. In addition, the company is promoting sales for the aftermarket (repair and replacement parts) and a shift toward a PLM (Product Lifecycle Management) business that combines these with Condition Monitoring Systems. Its structure aims to improve profitability through price pass-through, cost reduction, and enhancing the value-added mix of its product portfolio.
Company Strengths
Since its founding in 1916, the company has accumulated five core technologies: tribology (friction and lubrication), materials technology, analysis technology, mechatronics technology, and production technology. Achievements include the establishment of the "NSK Tribology Collaborative Research Center" with Institute of Science Tokyo (2023) and the commercialization of technology to suppress oxidative degradation of edible oil, among "2025
The company has manufacturing and sales bases in the Americas, Europe, China, ASEAN, India, and other regions, building a global structure comprising 90 consolidated subsidiaries and 18 affiliated companies. It serves diverse industrial customers in Automotive, machine tools, semiconductor manufacturing equipment, energy, and other sectors, diversifying dependence on any specific market. The company has also built up a track record in high-profitability areas such as the Americas aftermarket and semiconductor manufacturing equipment.
In FY2026 (ending March 2026), the net D/E ratio stood at 0.24x, maintaining a sound level well below the target (0.4x or less). The company has obtained an "A" rating from Rating and Investment Information, Inc. and an "A+" rating from Japan Credit Rating Agency, Ltd. It has also secured a ¥40 billion commitment line and a ¥50 billion commercial paper issuance framework, keeping liquidity risk under control.
ENVALITH's Perspective
Performance Trend
Revenue peaked at ¥938,098 million in FY2023, then declined to ¥788,867 million in FY2024, before recovering at an accelerating pace to ¥796,667 million in FY2025 and ¥911,644 million in FY2026. Operating profit also bottomed out at ¥27,391 million in FY2024, showing a clear improvement to ¥28,457 million in FY2025 and ¥38,812 million in FY2026. Factors behind the FY2026 revenue increase include external factors such as a gradual recovery in capital expenditure demand (Industrial Machinery) and steady automotive sales in the Americas, as well as company-specific factors such as the promotion of price pass-through for tariffs and the consolidation of NS&C (a new contribution of ¥100,554 million to Steering Business revenue). On the other hand, structural reform costs (one-time expenses) in the European business weighed on operating profit in the Industrial Machinery and Automotive segments. Operating cash flow improved to ¥97,806 million (from ¥82,176 million in the previous period), and the financial structure has also been strengthened.
Growth Strategy
Building the growth foundation for the next medium-term management plan through NTN integration, Steering business development, and expansion of AI/EV-compatible products
Entered into a basic agreement in May 2026 to promote management integration through the establishment of a joint holding company (via a share transfer). By combining the technology, quality, and management of both companies, the aim is to build a robust and sustainable business foundation, thereby achieving long-term and profitable growth and securing the position of Japan's industrial base in the world.
In September 2025, NS&C and its subsidiaries were brought into the scope of consolidation, establishing the Steering business as the third reportable segment. In FY2026 (ending March 2026), the Steering business recorded net sales of ¥100,554 million and operating profit of ¥7,730 million (including one-time gains and losses). For FY2027 (ending March 2027), net sales of the Steering business are forecast at ¥170,000 million (+69.1% year on year) with operating profit of ¥4,000 million.
Anticipating increased capital expenditure demand centered on semiconductor-related fields against the backdrop of expanding AI demand, the company is accelerating growth in the Industrial Machinery Business. In addition to steady demand trends in the Americas aftermarket and for semiconductor manufacturing equipment, the company is promoting expanded sales of high-value-added products such as Condition Monitoring Systems. For FY2027 (ending March 2027), net sales of the Industrial Machinery Business are forecast at ¥400,000 million (+6.0% year on year), with operating profit of ¥22,000 million (+75.1% year on year).
Strengthening the profit base of the Automotive Business by expanding EV/HEV-compatible products such as Ball Screws for Electro-Hydraulic Brake Systems and low-torque bearings. Continuing to promote the pass-through of tariffs into selling prices, securing the effect of increased revenue in the Americas. For FY2027 (ending March 2027), net sales of the Automotive Business are forecast at ¥400,000 million (-0.8% year on year), with operating profit of ¥18,000 million (+3.6% year on year).
In response to the deterioration of market conditions in the European manufacturing industry, the company is promoting structural reform of its European business in the Industrial Machinery and Automotive segments. In FY2026 (ending March 2026), one-time expenses were recorded, but the company aims to improve its medium- to long-term profitability through the completion of structural reform. Under the next medium-term management plan (with FY2027 (ending March 2027) as its first year), the company plans to promote further profit improvement and transformation of its product portfolio.
