Founded in 1945 (Showa 20), SEIKOUSHA CORPORAION is a specialized trading company connecting manufacturers of precision mechanical components with machinery manufacturers. Our business began with the distribution of bearings, thoroughly studying their types, sizes, and characteristics in order to provide the most suitable options for each customer. As Japan's manufacturing industry experienced significant growth, the demand for advanced mechanical components increased. In response, we were among the first in the industry to begin handling the newly introduced ball screws and linear guides. By collaborating with component manufacturers and customers’ engineers to improve the products, we accumulated extensive expertise and established ourselves as specialists in linear motion technology. Today, our product range has expanded to include a wide range of components, and we take pride in being a specialized trading company in the field of motion engineering.
