History
Our company has been devoted to the turning of bearings since it was founded in 1951. Our first president, Tatsuzo Nagatsuji, was a machine processing craftsman from a young age, and after opening his own company, he used his skills to turn special bearings, which resulted in the foundation for our company's distinctive small-lot, high-mix production.
In 1989, in order to respond to the times when added value was emphasized, we opened the Mie Factory in Ueno City, Mie Prefecture, and started introducing NC lathes. Processing with NC lathes was said to be unsuitable for machining bearings due to lead time and cost, but we established a production method that was comparable to that of single-purpose lathes.
Furthermore, in May 2006, in anticipation of further development, we moved our head office and factory to Iga City, Mie Prefecture, close to our Mie Factory.
By combining the technical capabilities we have cultivated thus far with high-tech machinery, we are striving to respond to this age of international competition and provide products that will satisfy our customers even more.
