Carbon Steel Stepped Shaft With Splined Shaft and Textured Midsection, Machined Shoulder Transitions

We machine this splined shaft with process controls to keep geometry consistent across runs. For this build, we manage major diameters, critical tolerance windows, and surface finish during machining and inspection per your drawing and quality requirements. Splined shaft shoulders, steps, and the textured midsection are held to the relationships you call out between datums. Before machining we review your released CAD and any supplied dimensioned print; machining and gear forming are performed at our Huaian facility, which holds ISO 9001:2015 and IATF‑16949. Quotes based on quantity and finish, finalized once we confirm your reference datums and related inspection focus.
