Sumitomo Cyclo® 6000 Series Speed Reducer: Internal Design & Structural Advantages
Explore the internal mechanical components of Sumitomo Cyclo® drives—delivering 500% shock load overload capacity, high torque density, and zero-gear tooth fatigue for heavy-duty industrial automation.
Why Choose Sumitomo Cyclo® Drive Technology? Unlike traditional involute gear teeth that operate on point contact and face shear stress, the Sumitomo Cyclo® drive operates on a unique smooth rolling contact profile. By distributing mechanical loads across multiple cycloidal discs and pins simultaneously, Cyclo® speed reducers withstand instantaneous shock loads up to 500% of their rated capacity without tooth breakage.
