Sumitomo Drive Technologies Cyclo Speed Reducer CNHX-612HY-15

The Sumitomo CNHX-612HY-15 is an SM-Cyclo 6000 Series inline cycloidal speed reducer manufactured by Sumitomo Machinery Corporation of America. The nameplate identifies part number PA067723, an input rating of 7.95 HP, 1750 input RPM, a 15:1 gear ratio, and a service factor of 1.0. The reducer belongs to Sumitomo's 612H frame size, a mid-to-large cast iron housing format well established in conveying, material handling, and general industrial drive applications. This is a standalone reducer without an integral motor, configured for NEMA C-face motor mounting via hollow input shaft. The output side presents a solid keyed shaft, visible in the provided photos along with a large flange mounting base. A Cyclo 6000 installation and quick-start guide is attached. The Cyclo mechanism achieves reduction through cycloidal disc action rather than involute tooth gearing, a design characterized by high shock load tolerance and compact reduction stages. Sumitomo cycloidal reducers in the 612H frame are widely used in aggregate, food processing, mining, and packaging equipment. Output shaft diameter and exact mounting dimensions were not confirmed from visible evidence and should be verified against Sumitomo Cyclo 6000 catalog data for frame 612H prior to installation.
