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:How does Welink Bearing ensure the low noise and high speed of the 628 bearing?

As a specialized manufacturer, Welink Bearing uses premium GCr15 chrome steel and highly automated precision grinding processes. Our 628 deep groove ball bearings strictly meet ABEC-5 (P5) precision and ZV3/ZV4 noise standards, ensuring stable, high-speed rotation up to 36,000 RPM for your cooling fans and micro motors.

Q:Can I get free samples of the 628 deep groove ball bearing for testing before bulk order?

Yes, absolutely. We support sample testing for our global B2B clients. We can provide free standard 628 miniature bearing samples (Open, ZZ, or 2RS types) for your quality evaluation. You only need to cover the express shipping cost. Lead time for samples is usually within 3-5 days.

Q:What seal types and clearance options do you offer for custom micro motor applications?

We are an industry and trade integrated company supporting OEM/ODM. For the 8x24x8mm 628 bearing, we offer Open type, ZZ (metal shields), and 2RS (rubber seals). The standard clearance is C0, but we can customize C2 or C3 clearance and use specific high-temperature grease based on your unique working environment and temperature requirements.
