China procurement desk
Ask the supplier to tie its offer, sample and paperwork to the same bearing revision. We coordinate the review and record open items for the buyer.

Check each quotation against the same drawing revision, seal construction and package contents.
Agree the sample, calibrated measuring instrument, drawing tolerance and method before measuring. Record the observed value and part identity.
Link the supplier lot and label photographs to packing records and assign any discrepancy before release.
Supplier-provided
Request the legal entity, site and dated quotation. Where an IATF 16949 or ISO 9001 document is requested, check the issuer, entity, scope and validity as quality-system evidence. Track product and market evidence separately by part and revision.
Third-party
Agree the sample count with the buyer and inspector. Compare bore, OD and width with the approved drawing. Record sensor-facing encoder orientation, label and pack contents. With a magnetic encoder, ask the inspector to note which face was checked and whether the pattern matches the buyer-approved reference. For a signal test, record the sensor, specified air gap, rotation direction and acceptance criterion in the check plan. Any endurance test needs a separately agreed load and duty cycle.
Buyer-approved
Attach the disposition to the SKU, revision and lot. Compare complete hubs and serviceable bearings on the same vehicle application. The hub line needs flange and sensor-interface verification. The bearing line needs bore, OD, width, preload procedure and kit contents, plus confirmation that the retained hub and housing meet the vehicle procedure. A second source adds options but needs its own disposition for the agreed sample.
