Custom Precision Spur & Helical Gears, Transmission Shafts for Reducer & New Energy Equipment

Meta description: Professional manufacturer of large helical gears, internal ring gears and precision gear shafts. Strict grinding process ensures low noise, high wear resistance for industrial transmission systems.

Transmission gears and gear shafts are the core load-bearing components of all heavy-duty industrial equipment, requiring ultra-high dimensional accuracy, surface finish and fatigue resistance. At Songben Xinke Precision, we focus on full-process custom machining of medium & large gears and matched transmission shafts to serve reducer factories, new energy motor manufacturers and engineering machinery brands worldwide.

We own complete gear processing equipment: CNC gear hobbing machines, German imported gear grinders, vertical lathes and cylindrical grinders. We can fabricate helical gears, spur gears, internal ring gears and integrated gear shafts with an outer diameter up to 2000mm, gear precision reaching AGMA 8~10 grade.

For matched gear shafts, we control coaxiality and roundness within 0.01mm through fine turning and precision grinding. Our production covers motor spindle, reducer output shaft, engineering machinery transmission shaft and wind power auxiliary shaft. All gear parts support heat treatment such as carburizing and quenching to improve hardness and service life under heavy load.

Our internal full inspection system includes dedicated gear testing machines, CMM and optical detectors to test tooth profile, tooth pitch and surface roughness 100% before delivery. We solve common pain points of overseas clients: unstable gear precision, loud operation noise and short service life under long-time heavy load.

We accept customized orders according to international gear standards. If you are looking for a long-term supplier of heavy-duty transmission gear and shaft parts, send us your gear drawing for free technical evaluation and competitive factory direct price
