Cast Steel Shaft Component with Flighted Auger Screw Shaft and Stepped End Sections

Major helix pitch, outside diameter tolerance, and shaft step dimensions are the governing callouts for a flighted auger screw shaft; helix pitch error accumulates over shaft length and causes uneven feed rate, while step diameter controls the fit to bearing housings at both ends. Chongqing Xinxin Zhiquan Machinery Manufacturing (Tongliang District, Chongqing) CNC-mills this steel flighted auger screw shaft, with helix pitch, major OD, and shaft step diameters produced to your released dimensions tolerances. IATF16949 certification at Xinxin Zhiquan's Chongqing facility (in excess of 20,000 m²) governs inspection traceability for agricultural machinery, conveying equipment, and automotive component applications. Painting and coating are available for corrosion protection on finished shaft surfaces, serving fasteners, mechanical and electrical (others), and motorcycle applications.
