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 NKI and RNA bearings?
A:
NKI bearings have an inner ring, while RNA bearings do not. RNA bearings use the shaft surface as the rolling surface.
Q:What is the required surface hardness for shafts used with NKI bearings?
A:
The journal surface hardness must be not lower than HRC60 with a roughness ra value not more than 0.63um.
Q:Can these bearings be used in high-speed applications?
A:
Yes, the cage design reduces friction, making them suitable for components with higher rotational speeds.
Q:Are sealed versions of these bearings available?
A:
Yes, sealed needle roller bearings are available with one or two seals, pre-filled with lithium-based grease.
Q:What are the payment terms accepted?
A:
We accept LC, T/T, D/P, PayPal, Western Union, and small-amount payments.
