Our gears continue to deliver the drive solution.
Gears, bearings, and screws have long been regarded as the “three essential elements of machinery,” indispensable for industrial development.
Among them, gears have been widely utilized in fields such as steelmaking and transportation machinery, making significant contributions to the advancement of industry and culture.
In recent years, their importance has grown even further as a core component of power transmission systems that support the automation and scaling-up of industrial machinery.
Since our founding in 1916, we have built a solid reputation as a leading gear manufacturer, backed by more than a century of tradition and technological expertise. Leveraging this heritage, we deliver high-precision gear products that meet international standards and have established ourselves as a top brand in the industry.
Our products are widely used not only in Japan but also around the world in applications such as power generation facilities, cement mills, river pumps, conveyors, and cranes—supporting the very foundation of industry.
We have utilized the knowledge and experience gained from these successes to pursue research and development of new technology, new products, and applications that meet the requirements of gear transmissions for “compactness, weight-reduction, high efficiency, and high precision.”
As a member of the Sumitomo Heavy Industries Group, we operate under the global brand “Sumitomo Drive Technologies,” realizing our business mission “Deliver the best possible drive solutions to build a better tomorrow”.
Through innovative products and comprehensive service solutions, we strive to meet and exceed expectations, aiming for continuous evolution as the leading manufacturer of gear reducers.
