Founding
In November 1916 Yamaguchi Takehiko and his associates established Nippon Seiko K.K. in Shinagawa, Tokyo, with capital of ¥350,000, and began the production of bearings for the first time in Japan. The purpose was to make at home the rotating components the country had until then bought abroad, and plants were then set down close to where demand was — Fujisawa in November 1937, Otsu in November 1953, Ishibe in November 1959. In June 1960 the company set up Kita Nihon Seiko in Maebashi, Gunma Prefecture, to make steering gear, opening the way into the car components that lie outside the bearing itself, and in December 1962 it placed a sales company in New Jersey in the United States. The structure by which one technology — the component that rotates — carries two customer industries at once, motor cars and industrial machinery, was settled in this period.
The Decision
With a single component, the bearing, NSK has redrawn again and again both how far out it goes and how much of the work it keeps. In the decade from 1974 it put plants in Australia, Britain and the United States, switching from sales companies to local production in the face of import restrictions and high tariffs. A European share stuck at 3 per cent was undone in March 1990 by acquiring all the shares of UPI, the largest bearing maker in Britain, which secured it third place in the world by scale. In April 2004, after two consecutive years of bottom-line loss in the IT slump, it moved to a company with committees and separated execution from supervision. In April 2023 it carved out the loss-making steering business and sold a majority stake to an investment fund, then, once the earnings had been rebuilt, bought every share back two years later. Bringing a business it had sold back into consolidation within two years is what closed off its own road back to being a bearing specialist.
Today
Third in the world by scale, and still an operating margin of only 4.3 per cent. Revenue of $5.8B (¥912bn) in the year to March 2026 divided into $2.5B (¥403bn) from automotive, $2.4B (¥378bn) from industrial machinery and $636.1M (¥101bn) from steering, with segment profits of $110M (¥17bn), $79.7M (¥13bn) and $48.7M (¥8bn) respectively. The shape of the year to March 2019, when automotive at $6.3B (¥690bn) was two and a half times industrial machinery at $2.5B (¥270bn), has levelled out as automotive margins fell away and industrial machinery grew. Operating profit for the group as a whole was $245.3M (¥39bn) and profit for the year $144.8M (¥23bn). Revenue rose about a tenth from $5.3B (¥797bn) the year before because the steering business that had been sold was brought back into consolidation. The width of business the company gained in the 1960s by widening into car components is now being shifted the other way, towards lowering the automotive share.
Competition
First at home but third in the world, NSK fills the scale it lacks by combining with its own industry. In bearings the world order puts SKF of Sweden first at about 17.7 per cent, Schaeffler of Germany next, and NSK after them. Until the UPI purchase of 1990 its European share stood at 3 per cent, and taking in a network of manufacturing and sales in one piece is what lifted it to its present position. At home it stands alongside NTN, and on price in standard products it has been losing share to Chinese makers. On 12 May 2026 it announced a management integration with NTN under a jointly established holding company, which if realised would carry sales of $10.7B (¥1.7tn) and a simple sum of world share of about 24 per cent, ahead of SKF. On the premise that EVs need fewer bearings and that Japanese car output shrinks, competing for rank at home means less, and the two companies chose to go under the same holding company.

Founding Story

1916–1989The origin of Japanese-made bearings, and a widening manufacturing base

NSK was created in 1916 to make in Japan a component the country could otherwise only buy from Europe, and for the seventy years that followed it grew by putting down factories — first across Japan, then in the United States, Britain, Brazil, Singapore and Korea — until sales of $6.4M (¥2bn) in the year to March 1952 had reached $860.1M (¥204bn) by the year to March 1984. Every one of those sites bought reach and scale; every one of them also became fixed cost that the decades after would have to answer for.

It began as the first company in Japan to mass-produce bearings

In November 1916 Nippon Seiko was established in Shinagawa, Tokyo, with capital of ¥350,000[1]. It came into being on 8 November 1916 through the reorganisation of its predecessor, the partnership Nippon Seiko Goshi Kaisha, into a joint-stock company[2], and Yamaguchi Takehiko (山口武彦) became its first president[3]. It was the first company in Japan to begin the industrial production of bearings[4], and it set out as a specialist maker created to produce at home, rather than import, a component that is required for as long as the machines that transmit power keep turning — railways, machine tools, motor cars. In the Japan of that time almost every bearing was an import from Europe, and no mass-production technology had yet taken root in the country. Yamaguchi Takehiko, the founder, had seen through to the structure by which a component as small as a bearing underpins the precision and the reliability of the entire machinery industry[5]. The name NSK, from Nihon Seiko Kaisha, was in use from the founding years, and from the moment of its establishment this was a company that took upon itself the task of supporting, from below, the precision of Japan’s machinery industry.

From the founding through the years of post-war reconstruction, the emphasis lay on stacking up domestic production sites. The Fujisawa plant was raised in 1937, Otsu in 1953 and Ishibe in 1959, one after another[6], and in 1960 the company established Kita Nihon Seiko in Maebashi, Gunma Prefecture. That company was reorganised in later years into NSK Steering Systems[7], and it is the headwater of the steering business that half a century on would be the central actor in a carve-out. A seed planted in the founding years had, in effect, prepared the stage for a management decision in the twenty-first century. Keeping step with the post-war expansion of the car, electrical-equipment and machine-tool industries, NSK added domestic production capacity. It can be said to have consolidated its footing as a bearing maker that held standard and special products together.

In its founding years NSK advanced the domestic production of bearings under a connection with the Navy. Former Navy men stood at the centre of its engineering, and its production plans began under Navy support[8]. The first Japanese-made bearing, arrived at through repeated prototyping, was delivered to the Yokosuka Naval Arsenal, and the first bearing made in Japan for a domestic aircraft was likewise used as an NSK ball bearing[9]. On the civil side, tapered roller bearings were adopted for the DAT of Kaishinsha, the pioneer of the Japanese motor car[10], and the commercial base spread across both the Navy and general industry. Sales offices followed — Osaka first in 1920, then Nagoya, Kokura and Sapporo — extending the sales channels[11], and in 1932 NSK tapered roller bearings were chosen for the axles of the National Railways’ new petrol railcars. These were the first railway-vehicle bearings made in Japan[12]. At the Tamagawa plant, opened in 1935, the company moved to mass production on automatic machinery imported from Europe and America[13], and in wartime it mass-produced bearings for tanks and aircraft at the military’s request[14]. At the end of the war most of its plants were designated for reparations, but Tamagawa and Fujisawa were exempted[15] and remained as the footing for post-war rebuilding.

Going abroad in the 1960s, and a pivot towards car components

Once the post-war high-growth years began, Nippon Seiko started to extend its footing overseas. In December 1962 it established NSK Corporation in New Jersey in the United States[16], and in October 1963 NSK Deutschland in Düsseldorf, Germany[17], setting about building sales networks in the Americas and in Europe at the same time. Germany was the home ground of the bearing major Schaeffler, and placing a local base there was in itself a challenge. Breaking into the distribution networks that the established European and American makers had built was not easy, but NSK put its sales organisation in place in step with the global expansion of the car makers. It was also among the earliest instances of a Japanese bearing maker holding a full-scale sales network abroad, and the layout of overseas bases in the 1960s became the foundation that would support its later position as number three worldwide.

In 1964 it launched NSK-Warner as a joint venture with BorgWarner of the United States[18], deepening its involvement in components for car transmissions. Local production followed sales in stages — the Peterlee plant in Britain in 1974, the Clarinda plant in the United States in 1975[19]. The Saitama plant came on stream in 1975[20] and the Fukushima plant in 1984[21], adding capacity at home and abroad. Keeping step with the growth of the car industry, the company shifted its weight from a pure bearing maker to a bearing maker that also made car components. This change in the business structure became the axis of NSK’s management for the half-century that followed, and it was also the origin of a dependence on the car industry that it would carry as a distinguishing feature and a weakness at the same time.

Groundwork in Korea and China under the Cold War

In September 1987 NSK established NSK Korea in Changwon, South Korea[22]. It coincided with the period in which the Korean car industry was beginning to grow its exports, and NSK held a local manufacturing base there as a Japanese component maker. By the end of the 1980s NSK had laid bases across the main regions of the Americas, Europe and Asia, and had expanded the scale of its sales. At home it established the Fukushima plant in 1984[23], and abroad it had put in place an organisation covering almost every major region other than Eastern Europe and China. Riding the wave of industrialisation that followed South Korea’s economic development plans from the end of the 1970s, NSK raised its presence in the Asian markets and consolidated its international standing as a Japanese bearing maker. The reading that placed local bases just before car production in the countries of Asia got going fed directly into the growth in results in the 1990s.

Through the 1980s NSK was consolidating a leading position in the Japanese bearing market while hurrying to raise the share of sales earned overseas. Bearings are a capital-intensive business in which standard and special products are mixed together, and recovering the investment in plant requires both geographic spread and scale. The rush of base-building in this period created the physical foundation that would support the later global expansion, and it was the run-up to the acquisition of UPI in Britain, the entry into China and the entry into Poland in the 1990s[24]. It was a decade of firming the ground on which to go after large orders from the car industry, and the period in which NSK put in place the base from which to catch SKF and Schaeffler, the two European makers ahead of it. Competition with the European players might be favourable in the domestic market, but abroad the contest was decided by differences in the speed of localisation, and NSK was preparing the ground for the acquisition it would stake on in the 1990s.
