Stepped Cylindrical Shaft with Machined Pinion Gear Shaft and Axial Splines

Aluminium alloy selection for a machined pinion gear shaft with axial splines determines spline form accuracy and fatigue resistance at the spline root; 7075-T6 provides the hardness needed for anodised tooth flanks to survive repeated engagement cycles in power tool and motorsport gear trains, while 6061-T6 suits lighter-duty drives where machinability and cost take priority. Dongguan Jiarui Hardware Technology (Dongguan, Guangdong, founded 2012) turns and mills this aluminium machined pinion gear shaft with stepped cylindrical profile and axial splines using 5-axis milling, turning, and external cylindrical grinding at their north of 2,000 m² Dongguan facility, with spline profile, journal diameters, and runout validated per your drawing during first-piece verification. IATF 16949 and ISO 9001 certifications govern production traceability for automotive, electric motors, motorsport, and OEM manufacturing machined pinion gear shaft applications.
