Are you having trouble because there is nothing the same when replacing products? We can accommodate modifications of standard products or new designs and manufacturing at a low cost starting from just one unit!

A non-stop transmission capable of instantaneous and precise shifting even while rotating! With the slide key system, accurate shifting operations are possible whether in motion or at a standstill. Gears and shafts are made from chrome molybdenum steel and undergo carburizing hardening, ensuring ample strength. It operates quietly, is compact, lightweight, and economical. The installation of the transmission and reduction gear can be done at any angle—horizontal, vertical, or sideways. If you contact us, we will send detailed drawings, including dimensions, rotation speed, and gear ratios, via fax, mail, or email. Gears can be manufactured in modules ranging from 0.5 to 22. Compared to other companies' inverter products, our system has fewer failures, consumes less power, and is more economical! We have many models of reduction gears, speed increasers, transmissions, and forward/reverse switches that are not listed in the catalog. If you provide us with the power, horsepower, gear ratio, and reduction ratio, we will send you drawings of suitable models. Additionally, we can design and manufacture modifications to standard products or new designs at a low cost starting from one unit. We can produce equivalent products for Yamai Manufacturing, Oya Manufacturing, Daito Seiki, and Taniguchi Reduction Gear. We design and manufacture speed increasers for hydropower generation and wind power generation.
