Forged Flanged Shaft | Integrated Forging & CNC Machining
A flanged shaft is a one-piece shaft component with an integrated flange, designed to provide secure mounting, accurate positioning, and stable load transfer within mechanical assemblies. This structure is commonly specified in OEM equipment where alignment, repeatability, and long-term operational stability are important.
At Weforging, forged flanged shafts are manufactured through a coordinated process that combines hot forging and CNC machining. By controlling material flow during forging and applying precision machining to functional surfaces, we support consistent geometry, reliable dimensional accuracy, and efficient integration into applications such as hydraulic systems, gearboxes, and heavy industrial equipment.
What Is a Flanged Shaft?
A flanged shaft consists of a cylindrical shaft body with an integral flange formed as part of the same component. The flange typically provides a mounting surface with bolt holes or locating features, while the shaft section supports rotation, alignment, or torque transmission within an assembly.
This integrated design—often described as an integral flanged shaft or shaft with flange—supports consistent axial positioning and efficient load distribution. It is commonly specified on engineering drawings where secure installation and repeatable assembly are required.
Forged Flanged Shaft Manufacturing Process
Hot Forging for One-Piece Flanged Shafts
Forged flanged shafts are produced by hot forging, where heated steel billets are shaped into near-net geometries. This process allows continuous metal flow through the transition between the shaft and flange, supporting uniform mechanical characteristics throughout the component.
CNC Machining & Dimensional Control
After forging, CNC machining is applied to functional surfaces such as shaft diameters, flange faces, and mounting holes. Precision machining supports accurate tolerances, flat flange interfaces, and reliable assembly performance across production batches.
Key Advantages of Forged Flanged Shafts
Forged flanged shafts offer structural and manufacturing advantages for OEM applications where dimensional stability and repeatable assembly are important. Key advantages include:
One-Piece Integrated Structure
The shaft and flange are formed as a single component through forging, supporting stable geometry and consistent load transfer within the assembly.Controlled Material Flow
Hot forging allows continuous material flow through the shaft–flange transition, contributing to uniform material characteristics across functional areas.Dimensional Consistency After Machining
Coordinated forging and CNC machining processes support accurate tolerances on shaft diameters, flange faces, and mounting features.Suitability for Batch Production
Forged flanged shafts are well suited for small to medium batch OEM programs that require repeatable quality across production runs.
These advantages make forged flanged shafts a reliable solution for industrial equipment, gearboxes, and hydraulic assemblies.
