Automotive Steering Rack Pinion Shaft

Quotation assessment for this shaft component relies on the specific diameter of the smooth shank, the length and pitch of the serrated section, and the required surface finish. The part features a cylindrical body with a distinct transition to a heavily ribbed or splined mid-section, designed to provide high-friction interference fit or torque transmission within an assembly.

Manufacturing typically involves precision turning for the smooth ends and specialized forming or rolling processes to create the uniform serrations, ensuring consistent tooth profile and concentricity. Critical quality controls focus on the straightness of the shaft, the dimensional accuracy of the serrated zone to guarantee proper press-fit force, and the absence of burrs on the sharp edges of the ribs.

Leveraging IATF16949 certified production lines, the facility utilizes CNC lathes and precision thread rolling equipment to maintain tight tolerances on such rotational parts. Available inspection tools, including concentricity gauges and profile projectors, verify the geometric integrity of the serrated features. Buyers should provide detailed drawings specifying material grade, such as carbon or alloy steel, and any heat treatment requirements to receive an accurate production quote.
