Rectangular Gearbox Housing with Gearbox Housing Assembly and Splined Shaft Hub

Drone gearbox assemblies, automotive sub-drive units, and energy storage module drives use a gearbox housing assembly where bearing bore position tolerance and splined shaft hub bore concentricity together determine gear mesh alignment and shaft runout; bearing bore position outside ±0.02 mm shifts the shaft centreline off the design axis and changes tooth backlash beyond the allowable range, while splined hub bore concentricity error above 0.015 mm introduces runout at the gear pitch circle and generates tooth-to-tooth load variation at drive frequency. Foshan Zhengshang Precision Hardware (Foshan, Guangdong, ISO 9001, ISO 14001, ISO 45001 certified) CNC-mills this rectangular stainless gearbox housing assembly with splined shaft hub at their roughly 2,000 m² Foshan facility through CNC milling, milling & turning, and gear forming, with bearing bore position, splined hub concentricity, and housing face flatness cross-checked with your print at sample sign-off. Zhengshang serves automotive, medical equipment, drones, energy storage, and communication gearbox housing assembly applications. Output serves fasteners and toys and gifts industry buyers. Supply bearing bore position, splined hub concentricity, housing face flatness, and material with your enquiry. For a production quotation from our foshan office.
