AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier focused on bearings and power-transmission products. It offers broad customization and ODM services, but does not provide 3D software design, SDKs, or OEM services for popular brands, and reported no new products in the past year. ISO 9001 certification is stated. The supplier claims integrated R&D-production bases, automated equipment, measurement tools, and strict quality control, while finished products are checked by packing staff. Export activity is reported at 90% of sales, with self-operated import/export rights and one year of export experience. However, reported operating revenue, costs, gross profit, and operating profit for the stated periods are zero, and there is no overseas warehouse, overseas showroom, overseas agent or branch, or offline trade-show participation. After-sales capability is not sufficiently documented.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and its business scope includes bearing manufacturing, bearing sales, and high-speed precision heavy-duty bearings. This supports classification as a specialized bearing and industrial power-transmission supplier.

CertificationsThe supplier states that it holds an ISO 9001 supplier management-system certification. The provided information does not include the certificate number, issuing body, or validity period, but it is explicit evidence of certification holding.

After-Sales capabilityThe supplier has no in-stock service capacity, overseas warehouse, overseas showroom, overseas agents or branches, and offers overseas services in zero countries. Service-capability assessment also lacks written procedures or followed records, so the available evidence does not demonstrate a robust after-sales network.

Financial creditThe stated financial records report zero operating revenue, operating costs, gross profit, and operating profit for the listed periods. These figures provide explicit negative evidence regarding reported financial performance and therefore raise a material financial-credibility concern.

Production capacityThe business scope explicitly includes bearing manufacturing, including high-speed precision heavy-duty bearings. The supplier also claims integrated R&D-production bases, automated equipment, precise measuring tools, skilled operators, and strict process quality control, although the provided information does not quantify production capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. This is direct evidence of broad product customization capability, despite the absence of 3D software design services.

Product Q&A

Q:What are the exact dimensions and typical applications of 7204 angular contact ball bearings?

The 7204 bearing features a 20mm bore diameter (ID), 47mm outer diameter (OD), and 14mm width. It is specifically designed for high-speed, high-precision applications such as CNC machine tool spindles, high-frequency motors, woodworking routers, and industrial centrifuges.

Q:Does Welink Bearing provide paired angular contact bearings (DB, DF, DT)?

Yes, as a direct manufacturer, Welink supplies factory-matched pairs in DB (Back-to-Back for maximum moment stiffness), DF (Face-to-Face), and DT (Tandem) arrangements, pre-configured with light (GA), medium (GB), or heavy (GC) preload to meet exact OEM requirements.

Q:How does Welink ensure the precision and longevity of 7204 spindle bearings?

We utilize high-purity vacuum-degassed GCr15 chrome steel (or hybrid ceramic balls), precision super-finishing, and strict vibration testing (Z3/Z4). All 7204 precision bearings meet ISO 9001 quality compliance, delivering low noise and extended service life under demanding industrial conditions.
