Company History

The history of ISC began in April 1949 in Furukawa, Kawasaki-shi, under the name of Ishii Steel Ball Co., Ltd.  By April 1951, ISC had broadened its manufacturing capabilities to include small ball bearings. ISC recognized the growing demand for higher precision smaller components in various machinery and devices. The same year, the company foresaw the importance of miniature bearings and embarked on research and development, which by December led to the production and marketing of their ultra-small ball bearings.
With growth and expansion, the Fujisawa factory was relocated in September 1958, marking a new chapter in ISC’s history of development. The subsequent partnership with NSK Ltd. in May 1961 fortified the company’s capital and technical sales, ensuring continued innovation and increased production of miniature bearings.
The relentless pursuit of excellence led to recognition along with Industry certifications, reflecting ISC’s commitment to quality and excellence. ISC obtained specification approval from the Ministry of Transportation Aviation Bureau in December 1967. ISC has earned ISO certifications for its products and operates its factories dedicated to environmental considerations for all processes. 
The company’s growth necessitated the establishment of additional sales offices, first in Osaka City in April 1972 and then in Matsumoto City, Nagano Prefecture, in December 1979. The increasing demand led to the establishment of NSK Micro Precision Co., Ltd. as a wholly owned subsidiary, emphasizing ISC’s significant role in the precision miniature component and bearing industry.
Renamed NSK Micro Precision Co., Ltd. in October 1979, ISC commemorated its 30th anniversary with a commitment to continue advancing its technological edge and market reach. This dedication was further recognized through various certifications, including the prestigious IATF16949 and ISO45001, underscoring ISC’s position as a leader in the precision manufacturing sector.
