About Us
NSK History

High quality and trust built up over 140 years history since the founding of our company

Our business started with manufacturing springs for rickshaws, then progressed to making springs for automobiles, then to suppling OEM. The history since our founding is shown below.

Evolution of the Business

The Beginning
from Blacksmith to Manufacturer of Rickshaw Springs

Our history starts with Masakichi Nakano, son of a swordsmith who became the first spring craftsman and set up the company in 1876. He started the business of making and galvanizing springs for rickshaws at Shiba-Shinbori in Tokyo, and the company has continued operations for over 140 years to this day.

Manufacturing of Automobile Springs

Nakano Spring Works was established at Nishi-Shibaura, Tokyo in 1927 and began manufacture of bumpers and wheel-shafts as well as springs for automobiles. Multi-leaf springs for military tanks as well as leaf springs for domestic and foreign (American) automobiles were produced. Exports started to the Middle East, Latin America, South East Asia and African markets.

OEM Products and NSK Brand Products

The company name was changed to Nakano Spring Company Limited in 1948, and in 1963 the new Akishima Plant (approx. 9,000m2) was completed. With better quality and improved production technology, a wide range of OEM and NSK Brand products were introduced. The technology and know-how gained has been handed down within the company and is now a great asset.

New Product Development

In addition to the production of multi-leaf springs, production facilities to manufacture parabolic leaf springs were installed in 2006 and this added a whole new dimension to the product line-up. An efficient production system was implemented which made it possible to offer a wide range of products while enabling small volume orders to be accepted and also reduce delivery lead time.

Towards the Future
–Aiming for Still Higher Quality

In 1989 the new Production Administration Building was completed at Akishima Plant to monitor design and production quality control. In addition, ISO certification was acquired and factory floorspace was expanded, all towards further improving quality and production technology. We strive to further develop our business and offer better customer service and to achieve higher level of customer satisfaction.
