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 of 6905-2RS bearing?

The 6905-2RS thin section bearing measures 25mm (inner diameter) * 42mm (outer diameter) * 9mm (width/thickness). It features double rubber seals and is part of the 69 series ultra-light bearing family.

Q:What is the difference between 6905 and 6205 bearings?

The 6905 bearing is a thin-section bearing with dimensions 25*42*9mm (9mm thick), while the 6205 is a standard bearing with dimensions 25*52*15mm (15mm thick). 6905 is ideal for space-limited applications requiring compact design.

Q:What is the maximum speed for 6905-2RS bearing?

The 6905-2RS bearing supports limiting speeds of 16,000 RPM with grease lubrication and 19,000 RPM with oil lubrication. The rubber seals help retain lubrication and protect against contaminants at high speeds.

Q:Can 6905-2RS bearings be used in vacuum cleaner motors?

Yes, 6905-2RS bearings are specifically designed for vacuum cleaner motors and portable cleaning equipment. The compact 9mm thickness and double rubber seals make them ideal for high-speed, dust-prone environments.

Q:What material and load capacity does Welink 6905 bearing have?

Our 6905 bearings are manufactured from Chrome Steel (GCr15) with pressed steel or nylon cages. They have a dynamic load rating of 9.4 kN and static load rating of 5.85 kN, suitable for light to medium load applications.
