AI-Powered supplier vetting

SummaryCHANGZHOU NANYI BEARING CO., LTD. is identified as a professional technical supplier offering sample-based, design-based, minor, and flexible customization, as well as ODM and OEM services. It has documented finished-product inspection instructions, written warehouse-control procedures with records, in-stock capacity, and stated lead times within 15 workdays in both peak and off-season periods. However, the available information shows no 3D software design, SDK, overseas warehouse, overseas branch or agent, overseas showroom, or offline trade-show capability. The supplier has one R&D engineer, no new products reported in the past year, and no quality-control testing equipment reported. No valid manufacturing-capacity contract with related subcontractors is available. Export activity and buyer-linked transaction records are present, including ACROSS BEARING, but certification and detailed financial strength cannot be verified from the provided slices.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and is associated with spherical roller bearing products. The records identify CHANGZHOU NANYI BEARING CO., LTD. as the supplier, but do not establish its exact legal manufacturing status.

After-Sales capabilityThe supplier’s R&D engineer responsibilities include providing samples according to customer requirements and after-sales service, and non-conforming units are repaired and re-inspected. However, it has no overseas agents or branches, overseas warehouse, or overseas showroom, limiting evidence of local overseas support.

R&D capabilityThe supplier offers ODM services and has one R&D engineer, but reported no new products in the past year and has no available SDK. Its stated R&D role focuses on customer-requested samples and after-sales service rather than documented product innovation.

Production capacityThe supplier reports in-stock capacity, lead times within 15 workdays in both peak and off-season, and written inspection and warehouse-control procedures. Nevertheless, it has no valid manufacturing-capacity contract with related subcontractors and reports zero quality-control test equipment, creating explicit production-control weaknesses.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, minor customization, and flexible customization. It also provides ODM and OEM services, although it does not provide 3D software design services.

Client casesThe supplier reports that 51%–70% of total sales come from exports and has exported goods for five years. Trade records associate it with buyer ACROSS BEARING and identify shipments involving India, but the slices do not provide customer performance evaluations or a broader verified customer portfolio.
