Product Overview
This high precision shaft is CNC machined from SUS304 stainless steel, designed for pulley assemblies and mechanical systems that require accurate diameter control, stable rotation, and reliable alignment. With a compact stepped structure and controlled tolerances, the shaft is suitable for precision applications where consistent performance and dimensional stability are critical.
Structural Design
The component features a one-piece stepped shaft construction, produced from solid stainless steel bar stock. A larger central diameter provides structural support and positioning, while both ends transition into smaller shaft sections through well-defined shoulders. This stepped design allows the shaft to function effectively as a pulley shaft, ensuring proper axial location and concentricity when assembled with pulleys, bearings, or mating components.
