AI-Powered supplier vetting

SummaryZaozhuang Yiding Bearing Co., Ltd. is a China-based trading company established in 2014, specializing in bearing export, sales, production coordination, and after-sales service. It offers multiple bearing categories and reports broad export coverage, with peak- and off-peak fulfillment stated as within 15 working days. The supplier describes quality-assurance and management systems, but supplier-management certification is recorded as NIL. Its stated workforce is seven employees, including 6–10 quality-control staff in another record, creating an internal inconsistency. R&D experience is limited to one year, and no direct customization capability or named customer portfolio is provided. A single trade transaction is recorded, which is insufficient to establish broad customer-case experience. Financial credibility cannot be assessed because the available financial-related information is incomplete and monetary data is excluded.

Supplier typeThe supplier is explicitly identified as a trading company and limited company headquartered in Zaozhuang, Shandong, China. Its stated operations include bearing export, selling, production, and after-sales service, but the available classification identifies it primarily as a trading company.

CertificationsSupplier-management-system certification is explicitly recorded as NIL. Although the supplier claims to have established a strict quality-assurance system, no formal certification is evidenced in the provided information.

After-Sales capabilityThe supplier explicitly states that it provides after-sales service and describes a professional management system covering pre- and post-sales activities. Its company background also lists after-service as part of its operations, providing positive but self-reported evidence of capability.

Production capacityThe supplier reports two production lines, stated product output for ball screws, roller bearings, and ball bearings, and fulfillment within 15 working days in both peak and off-peak periods. However, the company is classified as a trading company and the production information is not independently supported, so capability is evidenced but not fully verifiable.

Product Q&A

Q:What is the difference between bearings with and without inner rings?

Bearings without inner rings (RNA/NK type) allow the shaft surface to serve as the rolling surface, requiring hardness >= HRC60. Bearings with inner rings (NA/NKI type) include a separate inner ring, outer ring, rollers, and cage for easier installation.

Q:What are the surface requirements for shafts used with inner-ringless bearings?

The journal surface must have a hardness not lower than HRC60 and a surface roughness (Ra) value not more than 0.63um to ensure high life and running accuracy.

Q:How does the sealed version (2RS) improve bearing performance?

The 2RS sealed version prevents dirt intrusion and is pre-filled with lithium-based grease. The inner ring is wider than the outer ring to maintain a good seal even with slight shaft displacement.

Q:What is the average lead time for orders?

The average lead time is within 15 workdays for both peak season and off-season periods.

Q:What payment terms are accepted?

We accept LC, T/T, D/P, PayPal, Western Union, and small-amount payments.
