hollow shaft cycloidal gear reducer rv-320ca


The precision cycloidal pinwheel RV-320CA gear reducer is also a cycloidal pinwheel planetary reducer, usually a 2-stage reduction mechanism, with high transmission rigidity, large transmission ratio, stable transmission, small inertia, large output torque, small size, strong impact resistance features.

It is commonly used in industrial robots, CNC machining machines, medical equipment, welding positioners, AGV trolleys, solar and wind energy, and other fields that require high-precision positioning.

Nabtesco of Japan is the world’s largest manufacturer of precision cycloidal pinwheel RV gear reducers, but at present, with China’s technical level, it can also produce RV-320CA of the same quality and accuracy at half the price of the Japanese brand. Genius Robotics Zhenkang is this such a company.
