About this product

6C is an exact named standard C-form RV precision reducer in Nantong Zhenkang's official mechanical transmission portfolio. It belongs to the manufacturer's robotics-component RV family. The Chinese table gives a rated output torque of 59 N·m at 30 rpm and a mass of 1.5 kg. Detailed dimensions, operating torque and input-power points are retained in Specifications. The paired manufacturer cover shows front and rear series views rather than a verified exact size. Exact-model release timing and current availability remain unverified. Cover image: Manufacturer series image; size may vary.
