Product OverviewRP80 is a planetary gear motor / gearbox with an 80 mm outer diameter, standard 19 mm keyed output shaft and industrial ball bearings. It provides reduction ratios from 1:3.55 up to 1:138 and rated torque up to 80 N·m (120 N·m short-term). The design supports high radial and axial loads for heavy-duty industrial automation and outdoor applications.
Key Facts for Engineering Buyers- Product category: Planetary Gear Motor / Gearbox
- Model: RP80
- Brand / manufacturer: KWC Motor, Dongguan KWC Machinery Co., Ltd.
- Outer diameter: 80 mm
