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 specifications of 6905 bearing?

The 6905 deep groove ball bearing has dimensions of 25mm (bore) * 42mm (outer diameter) * 9mm (width). It features a dynamic load rating of 7.0-8.75 kN, static load rating of 4.3-4.5 kN, and maximum speed of 14,000-19,000 RPM. Made from GCr15 chrome steel with steel cage construction.

Q:What is the difference between 6905 and 61905 bearings?

The 6905 and 61905 are the same bearing with different naming conventions. Both are thin section deep groove ball bearings with 25x42x9mm dimensions. The 6905 follows ISO metric standards, while 61905 is an alternative designation used by some manufacturers.

Q:Which clearance should I choose for 6905 bearing - C0, C3, or C4?

C0 (normal clearance) suits standard applications at room temperature. C3 clearance is recommended for high-speed motors (>10,000 RPM) or elevated temperatures as it provides 50-100% more clearance. C4 offers maximum clearance for extreme conditions. Choose based on operating temperature and speed requirements.

Q:What applications commonly use 6905 thin section bearings?

6905 bearings are widely used in electric motors, portable vacuum cleaners, washing machine motors, automotive components, industrial fans, power tools, and home appliances. The thin 9mm cross-section makes them ideal for space-constrained applications requiring high-speed rotation.

Q:Can 6905 bearing handle axial loads or only radial loads?

While primarily designed for radial loads, 6905 deep groove ball bearings can accommodate axial loads in both directions due to their deep raceway grooves. They typically handle axial loads up to 50% of their radial load capacity, making them versatile for combined load applications.
