This product has proven to be reliable in assist devices in welfare, medical, and workplace settings.
【Features】 ■ Coaxial speed reduction of motor. ■ By stacking reducers in a multi-stage configuration, the speed ratio can be increased. For example, with a first-stage speed ratio of 5:1 and a second-stage ratio of 3:1, the total speed reduction of a 2-stage unit becomes 15:1. ■ By reversing the input and output, this product can be used as a speed increaser. ■ Since this is a unique product that only consists of the planetary gear mechanism, we leave the design of the casing/housing up to the customer. * For more information on installation and casing, please download the "Design Guide" below. ■ The high backdrivability of this product has led to a rapid increase of adoption in assist devices in medical, nursing, and workplace settings!

Using our unified and reliable manufacturing system, Matex responds to your requests for further space-saving and high torque specifications by providing a wide range of standard Planetary Gear Modules (plastic, sintered steel alloy, machined steel). Our products can achieve high torque levels through coaxial connection of multiple stages (in such a multi-stage configuration, the reduction ratios of the individual stages are multiplied, e.g. 4x5=20). We handle everything from custom design to mass production. Our company also engages in injection molding and metal processing. Feel free to check our company information section for more details. *You can download the detailed Matex Planetary Gear Reducer catalog below. ■ Features of Matex Planetary Gear Modules 1. Efficiency: 95% for single-stage use, 90% for two-stage use. 2. Noise: Gear noise is significantly reduced thanks to a special structure holding the planetary load. Load fluctuations do not affect noise levels. 3. Equal Load Distribution Mechanism: The conventional disadvantages of Planetary Gear mechanisms have been resolved by our equal load distribution mechanism. 4. High Torque: A unit that pursues the planetary equal load holding mechanism achieves compact size and high torque. *For more details, please download the materials or feel free to contact us.
