Stepped Flanged Shaft Component with Turned Cylindrical Shaft and Internal Axial Bore

Shaft steel selection determines machinability and the achievable surface finish grade on journal and shoulder features; a turned cylindrical shaft in free-machining carbon steel reaches lower Ra values on the bearing journal than an equivalent alloy steel shaft machined at the same cutting parameters, where tool wear varies the finish across the run. Ningbo Zhenhai Weiye Machinery (Ningbo, Zhejiang) turns this stepped flanged shaft with internal axial bore using 40 CNC lathes and external cylindrical grinders, with major diameter, shoulder position, and journal surface finish produced to your specification tolerances. ISO 9001 certification at Weiye's Ningbo facility governs traceability for automotive, electric motor, and oil & gas shaft applications across their broad industry base.
