Carbon Steel Splined Gear Shaft With External Longitudinal Splines and Stepped Cylindrical Profile

We manufacture splined gear shaft to keep fit consistent across repeat batches. For the splined gear shaft, we set checkpoints around specified critical tolerance limit, surface finish requirement, and material grade group, with lot traceability to the release and recorded inspection results. Production follows the supplied dimensioned print with inspection callouts to maintain correlation to the released file. Lead times are set by batch size and confirmed critical parameters, with scheduling adjusted to the agreed production scope. Jiangsu Zhonggu Axle in Huaian holds IATF 16949 certification and supports precision gear machining.
