What is the bore tolerance standard?

Bore hole tolerances are machined to H7 precision grade, ensuring precise fitting and strict concentricity control.

Is the coupling suitable for harsh environments?

Yes, the closed metal housing and sealed lubrication design protect against dust, moisture, and oil contamination, making it suitable for harsh conditions.

AI-Powered supplier vetting

SummaryThe supplier is a limited trading company in Xingtai, Hebei, associated with manufacturing-sector companies and offering a broad range of couplings. It reports ISO 9001 certification, five production lines, stated coupling output of 3,000,000 sets, 133 employees, and fewer than five quality-control staff. Customization and ODM services are available, supported by CAD and Photoshop capabilities and 13 R&D patents, but no new products were reported in the past year, no SDK is available, and key R&D documentation is absent. Service governance is weak: no written procedures or records were provided for service assessment, corrective actions, or complaint handling. The supplier has in-stock capacity and self-operated import/export rights, but no overseas warehouse, showroom, or overseas service-country coverage. Financial evidence is limited to referenced years and cannot establish credibility. No customer cases were provided.

CertificationsThe supplier reports holding ISO 9001 certification. The provided information does not include the certificate number, validity period, scope, or issuing body, but it is explicit evidence of a management-system certification.

After-Sales capabilityAfter-sales and service-management controls appear weak because no written procedures or records were provided for service assessment, corrective and preventive actions, or complaint handling. The supplier has in-stock capacity and self-operated import/export rights, but lacks overseas warehouses, overseas showrooms, and overseas service-country coverage.

Production capacityThe supplier reports five production lines, 133 employees, and coupling output of 3,000,000 sets, with in-stock service capacity. However, there is no valid contract between the factory and its related subcontractor, which creates a documented manufacturing-governance deficiency.

Customization capabilityThe supplier explicitly provides customization from designs, full customization, minor customization, flexible customization, and ODM services. Its R&D engineers are responsible for customizing products to customer needs, although the absence of available R&D audit documentation limits verification of the underlying development process.
