Open questions
A missing dimension stays open until it has a source and revision. If two references share a bore but differ in encoder side, keep both options visible until the buyer checks the vehicle application.
Independent procurement
About National Bearings
We are an independent China sourcing and procurement coordination service. Our role is to organize specifications, supplier quotes and evidence for buyer review.
How a brief moves through the desk
Open the request
Give each part a line number. Where a supplier uses a different reference, record both references and their fitment scope.
Resolve fitment questions
Ask suppliers for dimensional drawings and flag exceptions such as a missing ABS encoder or a different seal orientation.
Prepare the buyer handoff
Keep the selected quote, sample decision and packing instructions together, with the revision visible on each record.
What we keep visible
Quote assumptions
Compare supplier stock by stated SKU and revision. If the order needs custom packaging or a revised hardware kit, record sample and label approval separately from the bearing price.
Decision history
Sample changes and accepted exceptions belong with the final part list and the person who approved them.
Roles on a sourcing request
Specification intake
Collect the buyer's part references and define the missing fields before sending the same brief to suppliers.
Verification and shipment coordination
Connect buyer approval, any third-party inspection request and the packing information needed by the appointed freight partner.
Who supplies the evidence
- Supplier drawings
- Third-party findings
- Buyer approvals
When a supplier submits an IATF 16949 or ISO 9001 certificate, check the organization, site, scope and validity. Product or test evidence is checked separately against the quoted SKU and market.
