About

About Matex Co.,Ltd. Matex is a leading Gear Reducer manufacturer from Osaka, Japan, founded in 1921. Our main focus is set on designing, developing, and manufacturing Gear Reducers, including Planetary Gear Modules and Gearboxes, to a world-class standard. Matex is most well-known for its caseless Planetary Gear Reducer, a unique product dubbed the Planetary Gear Module. Its compact and sleek design allows for easy integration into any custom gearbox, while our innovative structure reduces excess noise significantly. With a standard lineup of outer diameter sizes ranging from 26mm to 200mm, and output torque numbers ranging from 0.8Nm to 1300Nm, these Planetary Gear Modules cover a wide range of applications. Yet, our standard products only make up one part of Matex's various capabilities. Over 80% of Matex's Gear Reducer sales are semi-custom or custom designs. Matex tirelessly prioritizes customer requirements, providing full support from design to mass production. We have a well-proven track record designing, developing, and manufacturing tailored custom Gear Reducers in a wide range of fields. In the United States alone, Matex has contributed to a space agency moon rover (aeronautical), EOD robots (defense), vaccine pumps (medical), and electric pumps (manufacturing), among many other examples. Matex owns 3 mass-production facilities in Japan, the Philippines, and China, ensuring a reliable supply line and competitive pricing. We can also flexibly respond to commissioned development, manufacturing, and assembly of other mechanical parts such as Electric Actuators, Power Units, Pumps, and Injection Molded Plastic Parts, so feel free to consult us on any project proposal.
