Engineered for high-torque mechanical assemblies and motor drive systems, these Precision CNC Turned Stepped Shafts provide exceptional concentricity, durability, and reliable power transmission. Precision-machined from high-tensile steel, each shaft features multi-diameter step profiles along with precision-cut external keyway slots and internal keyway bores to secure gears, pulleys, or couplings without slippage.
Multi-Step CNC Lathe Machining: Turned with high precision to provide exact tolerances across multiple shaft diameters for precise bearing and sleeve fitment.
Dual Keyway Fastening System: Features an external keyway slot on the upper shaft section and an internal keyway bore at the base for positive torque transfer.
Integrated Oil/Set-Screw Port: Includes a precision-drilled cross hole on the main housing body for lubrication access or locking set-screws.
High-Strength Steel Construction: Built to withstand severe rotational torque, axial loads, and continuous mechanical stress.
Fine Machined Surface Finish: Smooth ground-finish journal surfaces minimize friction, heat generation, and wear on adjacent bearings.
