Bearing buyer question
What Certificates and Inspection Reports Should a China Bearing Supplier Provide?
Use two evidence layers: current management-system certificates that match the legal entity, site and scope, and order-specific records that identify the purchased bearing, drawing revision and batch.
Information required for a checkable answer
- Certificate holder, site, scope, issuer and validity
- Material certificate linked to heat or batch where required
- Heat-treatment and hardness records where specified
- Dimensional and runout inspection results
- Gauge or equipment identity where agreed
- Final inspection and nonconformity disposition
- Batch marking, packing list and document index
Certificates and order evidence
Do not accept a logo or an undated certificate screenshot as proof. Check the certificate holder, site address, scope, standard, issuer, certificate number and validity. Then request order-specific records for the bearing you are buying.
Available documents are confirmed against the selected supplier, specific product and order. A document is not promised until its holder, scope and availability have been checked.
Lead time and delivery confirmation
A reliable lead time is issued after the drawing revision, material route, quantity, tooling, inspection scope and packing are fixed. Ask for separate dates for drawing approval, material readiness, first article, batch completion and dispatch.
Recommended RFQ package
Send the controlled drawing or model, application conditions, quantity, destination country and the records you require. We will identify missing inputs and reply with the review status before a production commitment.
Use the bearing RFQ checklistFrequently asked questions
Does ISO 9001 prove product performance?
No. It supports a quality-management system. Product conformity still requires an approved specification and order-specific inspection evidence.
Can one certificate cover every factory?
Not automatically. Check the legal entity, manufacturing address and certified scope shown on the certificate.
How do I link reports to delivered parts?
Define the drawing or part number, revision, purchase order, lot or heat number, quantity and marking convention on the document package.
