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 main applications of the 673 miniature bearing?

The 673 miniature deep groove ball bearing features an ultra-compact size of 3mm (inner diameter) x 6mm (outer diameter) x 2.5mm (width). It is primarily designed for space-constrained applications like robot joints, micro motors, drones, and precision instruments.

Q:Can the 673 ball bearing stably handle high-speed micro motor applications?

Yes. Manufactured to ABEC-5 (P5) precision standards with optimized internal clearance (C3), our 673 bearings can achieve limiting speeds up to 65,000 RPM when grease-lubricated, ensuring smooth and low-friction operation.

Q:Do you offer stainless steel options for the 673 bearing for outdoor robotics?

Absolutely. While our standard 673 bearings are made from high-carbon GCr15 Chrome Steel for superior wear resistance, Welink Bearing also manufactures them in SUS440C Stainless Steel to meet strict anti-corrosion requirements in outdoor robotic or medical applications.
