cycloidal gearbox rv reducer-RV-27c


The hollow structure RV-27C cycloid gear reducer has the advantages of high transmission efficiency, low noise, compact structure, lightweight, small size, good reliability and stability, long life, and large reduction ratio range.

Lightweight and compact design, greatly reduced in size compared to traditional planetary reducers and can save installation space.

Genius Robotics Zhenkang is the largest professional manufacturer of precision cycloid RV gear reducers in China. The size, accuracy, speed ratio, and noise of the precision cycloid RV gear reducer produced are the same as those of Nabtesco in Japan.
