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:Is Welink Bearing a manufacturer, and where do you produce the 7204 angular contact bearings?

Yes, Welink Bearing is a verified industry and trade integrated manufacturer located in Fujian, China. We operate advanced grinding and assembly lines specifically dedicated to high-precision angular contact ball bearings like the 7204 series.

Q:Can I choose the contact angle and pairing type for the 7204 spindle bearing?

Absolutely. We manufacture the 7204 bearing with 15 Degree (C), 25 Degree (AC), and 40 Degree (B) contact angles to suit different axial load requirements. We also provide universal matching (DB, DF, DT pairs) to ensure optimal preload for your CNC spindles.

Q:What is your minimum order quantity (MOQ) and lead time for precision machine tool bearings?

We offer flexible MOQs to support your business. For standard P5/P4 grade 7204 bearings, we keep ready stock for fast dispatch within 3-5 days. For custom configurations (e.g., specific preload or brass cages), production lead time is typically 15-20 days for global delivery.
