Industrial furnace plant

In July 1958, the company began as a joint venture between Lindberg business division of General Signal, a world leader in the production of semiconductor manufacturing devices and of Koyo Seiko Co., Ltd., one of the world's largest bearing manufacturers. The goal was the starting of domestic production of industrial thermal processing furnaces in Japan. By July 1967, in order to expand the technological and sales ability of the division, it was reorganized into an independent company and renamed Koyo Lindberg Co., Ltd. The company combined the best of U.S. manufacturing technology with Japanese attention to detail and high quality, to supply the domestic and overseas markets with better products. With the technical cooperation of the companies, Koyo Lindberg was able to meet the needs of manufacturers of steel, automobiles, electrical and electronic components, LSIs and FPDs.
After the take over of General Signal by SPX, in April 1999 the 31 years and 9 months of this joint venture was broken up and absorbed into a new organization. The company belonged then 100% to Koyo Seiko. From October 1999, the company began under a new name: Koyo Thermo Systems Co., Ltd. In January 2006, Koyo Seiko merged with Toyoda Machine Works. Both companies belonged to Toyota group. The new company was renamed to JTEKT. Koyo Thermo Systems is now a 100% subsidiary of JTEKT and will achieve further breakthroughs to create the thermal processing of tomorrow.
