SummaryThe supplier manufactures and sells bearings, gears, transmission components, and related mechanical parts, with applications including automobiles, machine tools, motors, and other equipment. It reports IATF16949:2016 certification, 10 production lines, 6–10 quality-control staff, and standardized finished-product inspection instructions. Customization is offered from samples, designs, and full or minor specifications. However, no SDK is available, R&D experience evidence is limited, and no documented procedures or records were provided for service assessment, corrective actions, or complaint handling. The supplier has no overseas warehouse, showroom, agents, or branches, and has not participated in offline trade shows. Export sales are reported at 90%, but the supplier began exporting only one year ago. Financial figures are excluded in accordance with the privacy requirement.
