Fitment basis
OE reference, axle and drawing revision stay together. A superseding number needs an application record.
Our role
We are an independent China sourcing and procurement coordination service. The site name uses a brand search reference. The desk operates independently of the named brand and its sales channels.

A request for a front wheel bearing often arrives with a short catalogue description. Two offers may agree on nominal size yet differ in the ABS encoder orientation or the hardware included. A useful comparison starts by documenting which vehicle and axle each offer actually covers.
The procurement desk records the answers against the RFQ line. In a serviceable tapered roller bearing request, we would ask whether the cup and cone come as a matched set and whether the kit includes the correct seal lip. The supplier confirms the offered item, and the buyer reviews the evidence and approves any deviation.
Keep an unanswered fitment question visible until someone can close it with evidence.
OE reference, axle and drawing revision stay together. A superseding number needs an application record.
A single supplier simplifies sample and drawing control. Splitting orders can expand OE coverage, but each source needs a separate sample approval and traceable lot labels.
Track who supplied the evidence, who checks it and who approves deviations.

A category manager may compare the unit price while a workshop looks for a new retaining ring or axle nut. Put the buyer-approved parts list next to the supplier packing statement so the item ordered matches the kit the workshop expects.
For serviceable applications, record whether the hub and knuckle stay in place. For an integrated unit, ask for the hub flange drawing and sensor connection details so the supplier quotes the right scope.
Use the brief to flag any vehicle split, missing drawing or hardware question.
