AI-Powered supplier vetting

SummaryCHANGZHOU NANYI BEARING CO., LTD. is identified as a professional technical supplier offering OEM and ODM services and several forms of customization. It has documented inspection and warehouse-control procedures, inventory capability, and stated lead times within 15 working days in both peak and off-season periods. However, it does not provide 3D software design, has no overseas warehouse, showroom, agent, branch, or offline trade-show participation, and has no valid manufacturing-capacity contract with related subcontractors. Innovation evidence is limited: no new products were reported in the past year, there is no SDK, and only one R&D engineer is listed. Quality testing equipment is reported as zero, although non-conforming products are repaired and re-inspected. Export activity is documented, with 51%–70% of sales from exports and five years of export experience. Customer-case evidence consists of a buyer named ACROSS BEARING associated with bearing transactions.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and supplies spherical roller bearings. It also provides OEM and ODM services, indicating a manufacturing-oriented supplier profile.

After-Sales capabilityThe supplier reports after-sales responsibilities for its R&D engineer and handles non-conforming units through repair and re-inspection. However, it has no overseas warehouse, showroom, agent, or branch, which limits documented overseas service infrastructure.

R&D capabilityThe supplier offers customization, ODM, and OEM services, but reports no new products in the past year, no available SDK, and only one R&D engineer whose listed duties focus on customer samples and after-sales service. These facts show service-based design support but limited evidence of ongoing product innovation.

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

Client casesTrade records associate the supplier with buyer ACROSS BEARING in transactions involving spherical roller bearing types 23256 KMBW33C3 and 23240 KMBW33C3. This provides evidence of at least one identified buyer relationship and relevant product transactions, but the slices do not establish the scale, duration, or performance of the relationship.
