CNC Custom Precision Turning Milling Steel Engine Crank Hub for Performance Racing Automotive

CNC Custom Precision Turning Milling Steel Engine Crank Hub for Performance Racing Automotive. Machined on high-end multi-axis CNC centers to achieve micron-level concentricity tolerances, ensuring completely smooth, wobble-free rotation at extreme engine RPMs. Turned and milled from 100% certified high-tensile solid billet steel rather than brittle castings, maximizing structural burst limits under high torque loads. Features a precision-milled multi-hole mounting flange with perfect bolt-circle diameters to ensure rapid, error-free timing sprocket and harmonic balancer installation. We offer comprehensive custom manufacturing based on your engineering drawings or physical samples, easily adapting internal snouts, keyways, step depths, and heights. As an established factory, our integrated one-stop solution spans from raw material compliance and multi-axis turning to precision internal wire-cutting EDM and controlled hardening. Specially hardened to handle continuous high-frequency engine harmonic vibrations, severe drive alternations, and massive crankshaft keyway shear stresses. Treated with a heavy-duty, deep hard-anodized black oxide coating or specialized nitriding finish to permanently prevent environmental oxidation, surface scoring, and transit rust. Supported by high-output automated CNC machinery setups, we provide global B2B procurement networks with highly competitive direct wholesale factory pricing and reliable lead times.
