Scope and method

National Bearings procurement steps

We coordinate sourcing in China using one specification baseline, so each quote can be reviewed against the same fitment and commercial requirements.

What the comparison should show

Workstream	What goes on the record
Specification intake	OE and supplier reference, front or rear position, vehicle application, hub flange and ABS encoder interface where relevant. Mark any drawing revision still to be confirmed.
Quote comparison	Separate the bearing-only price from kit hardware, tooling or sample charges. Capture currency, unit basis, MOQ, lead-time trigger and the named place for each Incoterm.
Sample coordination	Ask the supplier to label the sample with SKU and revision. Record the buyer's disposition and ask whether the same revision will be supplied on the purchase order.
Inspection coordination	Define which dimensions and labels the inspector checks, the sampling method and who can accept an exception. A visual check of the seal lip leaves endurance and encoder performance to their agreed test methods.
Shipment checklist	Reconcile supplier packing lists by part and lot, confirm carton marks, and give the appointed freight partner the port and document requirements.

Set the baseline
Approve a line-by-line brief. Put dimensional ranges, kit inclusions and required documents on the same row as the OE cross reference.
Compare like for like
Single-supplier orders can simplify labels and change control. Multiple suppliers can expand coverage, with added work to normalize pack counts and link each shipment to the correct source.
Assign a decision owner
A supplier provides drawings and test records, a contracted inspector reports findings, and the buyer accepts or rejects the sample and any deviations. We coordinate the handoff between those parties.

Send your part list and name the checks you need before approval.
