Bearing buyer question
What Determines Custom Bearing Lead Time from China?
Custom bearing lead time is a chain of approved technical and production milestones. It cannot be confirmed from product type alone; drawing revision, raw material, tooling, heat treatment, prototype, quantity, inspection and packing all affect the date.
Information required for a checkable answer
- RFQ completeness and engineering review time
- Drawing approval and revision changes
- Material or forging availability
- Tooling, fixtures and dedicated gauges
- Machining, heat treatment and grinding route
- Prototype and buyer approval time
- Batch quantity, inspection, packing and transport
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.

When should the lead-time clock start?
State the commercial and technical start conditions, normally including order or deposit and approval of the controlled drawing and specifications.
How should a supplier report progress?
Use dated milestones with status and evidence for drawing approval, material, first article, batch production, inspection and dispatch.
Can an urgent order skip first-article approval?
Only through a documented buyer decision. Skipping an agreed validation step changes risk and should never happen silently.
