AI-Powered supplier vetting

SummaryLuoyang Huayang Special Heavy-Duty and Large Bearing Manufacturing Co., Ltd. presents itself as a professional bearing manufacturer established in 2000, producing multiple bearing categories and offering OEM, ODM, and broad customization services. Evidence supports international trading experience, with Europe among its export markets, 18 years of exporting, and exports representing 51%–70% of total sales. The supplier operates one production line and reports annual slewing ring bearing output of 6,000 sets, with one-month lead times in both peak and off-peak periods. Quality-related procedures exist, including finished-product inspection instructions and complaint-handling records, while supplier approval and corrective-action records are incomplete. ISO9001:2015 certification and recent fire-drill activity are reported. Innovation evidence is positive but limited: the supplier reports new products during the past year, while total R&D engineer experience is stated as one year. No overseas warehouse,...

Supplier typeThe supplier identifies itself as a professional bearing manufacturer established in 2000, with design, production, sales, marketing, and service activities. Its listed products cover slewing, thrust, taper roller, spherical roller, deep-groove, crossed roller, and other bearing types, indicating a specialized bearing-manufacturing profile rather than a general trading-only profile.

CertificationsThe supplier reports holding an ISO9001:2015 certificate. This is explicit certification evidence supporting its quality-management position, although no additional certifications are provided.

After-Sales capabilityThe supplier has a clear customer-complaint procedure with followed records, and it accepts multiple quotation and payment arrangements. However, it reports no overseas warehouse, showroom, agent, or branch, so local overseas service infrastructure is not demonstrated.

R&D capabilityThe supplier reports new products during the past year and provides ODM services, with customization from samples and designs. Evidence is limited by the stated total R&D engineer experience of one year and the absence of an available SDK, so innovation capability is supported but not strongly established across technical development resources.

Production capacityThe supplier operates one production line, reports annual slewing ring bearing output of 6,000 sets, and has CNC, crane, machine-tool, and radial-drilling equipment. Finished-product inspection instructions are uniformly followed, but the factory does not continuously reconcile quantities for every batch or mass-production run.

Customization capabilityBoth R&D and design-service records explicitly list customization from samples, customization from designs, full customization, minor customization, and flexible customization. The supplier also reports ODM and OEM service capabilities, providing direct evidence of broad customization support.

Client casesThe supplier reports providing OEM services for well-known brands and has 18 years of export experience, with Europe among its export markets and exports representing 51%–70% of total sales. These statements indicate commercial experience, but no named customers, project descriptions, or independently verifiable case details are supplied.
