PU series high-load servo motor dedicated precision planetary gearbox
Achieve high precision with the planetary gear system, and let's source a high-precision reducer (gearbox) that can accommodate servo motors and stepping motors from Taiwan.
Sesame Electric, specializing in the development and manufacturing of precision motors, reducers, and gearboxes, leverages its extensive experience to propose suitable power transmission devices to customers. [Japanese language support available] The newly developed high radial load dedicated planetary reducer and gearbox "PU Series" is designed for high positioning accuracy and compatibility with various brands of servo motors and stepping motors, making it a high-precision reducer and gearbox. The main features of the high radial load precision type planetary reducer "PU Series" are its radial and thrust load capacities. It offers low backlash, low noise, low temperature rise, high efficiency, long lifespan, and excellent lubrication effects, making it applicable to robot arms with orthogonal axes or various automated production lines. When arranged with precision gears and racks, it can support high rigidity and high precision for applications requiring long stroke servo localization.

We want to adopt overseas products, but it is often difficult to find a reliable company. Considering the time, cost, and risk involved in the adoption process, I believe there are many customers who give up. To support such customers, YTK provides services that allow you to leave everything from consideration to post-adoption support to us. In the increasingly diverse and competitive market, we strive to meet our customers' needs adequately, and we ask for your continued support as YTK aims to be a "helpful company."
