Bearing buyer question
Can I Order a Low-MOQ Prototype Custom Bearing from China?
Possibly. Prototype quantity depends on material minimums, tooling, process setup, heat treatment, grinding and inspection. State both prototype quantity and expected production demand so the supplier can propose a realistic route.
Information required for a checkable answer
- Prototype quantity and expected annual demand
- Drawing revision and critical characteristics
- Whether tooling or dedicated gauges are allowed
- Material minimum and substitute policy
- First-article inspection scope
- Functional test and acceptance method
- Target date and production ramp plan
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.

Why can one prototype cost much more per piece?
Engineering, tooling, setup, material minimums and inspection are spread over very few parts.
Should prototype and production use the same process?
The supplier should identify any process difference. A prototype made by a different route may not prove production capability.
What happens after prototype approval?
Freeze the drawing revision and approved deviations, then confirm production quantity, control plan, inspection sampling, marking, packing and delivery schedule.
