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 6704 bearing?

The 6704 thin section deep groove ball bearing features compact dimensions of 20mm inner diameter * 27mm outer diameter * 4mm width. It's manufactured from high-grade GCr15 chrome steel (equivalent to AISI 52100) with a sheet steel cage. The bearing offers a dynamic load rating of 1.30 kN, static load rating of 0.73 kN, and achieves limiting speeds up to 12,000 RPM with grease lubrication. Available in multiple seal configurations including ZZ, 2RS, 2RZ, and open types.

Q:What applications is the 6704 bearing suitable for?

The 6704 thin section bearing is ideal for space-constrained applications including: industrial robotics and collaborative robot arms, medical equipment (CT scanners, PET scanners, surgical robots), semiconductor manufacturing equipment, optical imaging devices, precision instruments, conveyor roller systems, and automation equipment. Its ultra-thin 4mm profile makes it perfect for applications where installation space is limited while maintaining high rotational performance.

Q:What is the difference between 6704 ZZ, 6704 2RS, and 6704 Open bearings?

The 6704 ZZ features dual metal shields for high-speed applications with minimal friction, suitable for clean environments. The 6704 2RS uses dual rubber NBR seals providing superior contamination protection for dusty or wet conditions, though with slightly lower speed capability. The 6704 Open type has no seals, offering the highest speed potential but requires external sealing. All variants are pre-lubricated and maintenance-free. Choose 2RS for harsh environments, ZZ for clean high-speed appl
