RV Gear Reducer

The RV (Rotary Vector) reducer is a high-precision, two-stage gearbox using planetary and cycloidal mechanisms. The input shaft drives a crankshaft via planetary gears, causing the cycloidal gear to move eccentrically and deliver high-torque, low-speed output through the flange. In industrial robotics, RV reducers are essential for joint accuracy—used in joints 1–4 for ≤20 kg payloads, and all six joints for heavier arms. Offered in E Series (solid shaft) and C Series (hollow shaft), traditional models need sealing, lubrication, and machining. Our flange-integrated RV reducers are factory-sealed, pre-lubricated, and pre-machined—ready for servo motor use out of the box.
