Cylindrical Stepped Housing Gearbox with Planetary Gear Reducer and Flanged Output Bolt Circle

In robotic actuators, automation drives, and industrial gear units, the housing bore concentricity and flange bolt-circle accuracy of a planetary gear reducer determine whether the transmission runs smoothly or generates backlash under load. SYGO machines this stepped cylindrical housing from alloy steel in Pinghu, holding bore diameter and flange face runout to your drawing tolerances through CNC milling and external cylindrical grinding. IATF 16949 and ISO 9001 certification at SYGO's Zhejiang facility governs machining control, in-process inspection, and shipment documentation; the same quality chain applied to automotive, aerospace, and bearing transmission components. 70 staff operate from our plant (approaching 4,000 m²) serving hydraulic, robotics, medical equipment, and precision measurement sectors. Send your housing drawing with bore tolerance and flange bolt-circle callout to receive a quotation, supplying military, agricultural machinery, and communication sectors.
