Micro Gearbox Shaft Assembly

Quotation for this shaft-hub assembly relies on verifying the press-fit tolerance between the metal pin and the black cylindrical sleeve, as well as the concentricity of the exposed bearing seat. The component features a slender stainless steel rod intersecting a compact housing, with one end terminating in a precision-machined bearing interface suitable for rotational support in confined spaces.

Manufacturing control focuses on maintaining strict perpendicularity between the shaft axis and the housing face to prevent wobble during high-speed operation. The black outer sleeve likely involves powder metallurgy sintering or injection molding, requiring consistent density and dimensional stability, while the metal shaft undergoes turning and grinding to achieve the necessary surface finish for low-friction rotation. Critical checkpoints include the inner diameter of the bearing seat and the interference fit strength at the shaft-sleeve junction.

Dongguan Kangsile Precision Technology supports the production of such micro-transmission components through integrated CNC machining and powder metallurgy capabilities. With IATF16949 and ISO 9001 certifications, the facility utilizes automated visual inspection systems and hardness testers to validate material properties and geometric tolerances.
