A cross reference identifies a candidate. Compare its drawing revision, ABS encoder, service scope and receiving-market evidence before treating two offers as equivalents.
Review the evidence matrixExample review sequence for a front wheel bearing. Values and limits come from the buyer’s application and the selected supplier’s agreed drawing.
Compare the OE cross reference, build range, axle and side. Two offers can share a cross reference while describing different hardware or ABS encoder ring revisions. Request the supersession chain and list the exact SKU and drawing revision on the quote.
Record bore, OD and width in mm against the drawing. An illustrative 42 × 80 × 36 mm envelope still leaves the bearing preload, seal lip and encoder requirements open. For hub flange runout, seat the sample on the agreed datum, zero the indicator at the specified track and record the full-revolution max-minus-min reading in mm. Log the mounting condition, gauge resolution and applicable drawing limit.
For a system certificate, verify the site, scope and validity. For SKU-level evidence, match the report reference, sample, test method, conditions and receiving-market requirement.
Agree the inspection method for ABS encoder ring side, pole count and wheel speed sensor interface where specified. Confirm the seal lip orientation and drawing revision before any comparison.
Compare included hardware, setup work and spares stocking. An integrated hub may reduce press work. A separate bearing can preserve the flange where the vehicle service procedure allows it.
Normalize quote quantity, currency, Incoterm and named place. A single supplier simplifies evidence handoff. A split award can cover additional references and needs lot-to-carton mapping for mixed-container loading.
Identify the vehicle, target market and unresolved fitment fields.
Line up offers by configuration, hardware and trade terms.
Match the sample and inspection scope to the quoted SKU.
Record the buyer’s decision and reconcile the shipment documents.
