2. Manufacturing Process: Cutting to size, CNC rough turning, stress-relief heat treatment by tempering, precision finish turning, cylindrical surface grinding, and final product inspection.

3. Dimensional Characteristics: The component features a multi‑step, stepped cylindrical shaft design, with the outer diameters of different sections varying in discrete steps to meet assembly requirements. Protruding shaft shoulders serve as axial locating stops. The two shafts have different stepped configurations to accommodate distinct assembly needs, and the entire shaft exhibits tight concentricity control, resulting in minimal runout during rotation and smooth operation. The shaft shoulders prevent axial movement of mounted components.

4. Surface Treatment: The entire component undergoes blackening for rust prevention, forming a matte protective film on the surface that helps slow down steel corrosion.

5. Product Applications: Used to assemble bearings, seals, and drive pulleys, it facilitates torque transmission and is widely employed in small-scale drive modules, assembly line drive units, and lightweight custom machinery.
