Precision Aluminium Shaft Component with Flanged Cylindrical Shaft and Drilled Flange Holes

Electric motor encoder shafts, drone propulsion drives, and bicycle bottom bracket spindles use a flanged cylindrical shaft where flange face runout and hole true position together determine whether the flange seats perpendicular to the rotation axis and whether mounting bolts load the joint in pure tension; flange face runout introduces a coning condition that produces bending stress in the fasteners, while hole position error forces bolts off their intended line of action. Dongguan Jiarui Hardware Technology (Dongguan, Guangdong, founded 2012) turns and mills this aluminium flanged cylindrical shaft with cylindrical body and drilled flange holes using turning, milling and turning, and surface grinding at their 2,000 m² of workshop space Dongguan facility, with shaft OD, flange face runout, and hole true position confirmed using your drawing as reference during in-process inspection. IATF 16949 and ISO 9001 certifications cover electric motors, drones, bicycle, and OEM manufacturing flanged cylindrical shaft applications, supporting automotive, aerospace, and medical equipment projects.
