What belongs on an RFQ line
Identity and geometry
- Vehicle record
- Send the OE cross reference, VIN or exact platform and build date, axle position and left/right side. If the vehicle record and sample disagree, flag the conflict for review.
- Physical envelope
- For a bearing, list bore, outer diameter and width in mm. For an assembly, add hub flange, pilot and mounting dimensions from a drawing.
Signal and service scope
- ABS interface
- Record the ABS encoder ring type and orientation. If the assembly includes a wheel speed sensor, identify its connector and cable routing.
- Kit contents
- Separate the double-row angular contact bearing, seal lip orientation, snap ring and axle nut into line items. Call out the bearing preload requirements from the vehicle service data where relevant.
Decision sequence
From cross reference to release
- 01
Clean the list
Split references by axle and flag supersessions for confirmation.
- 02
Normalize quotes
Align kit contents, trade terms, packaging and exclusions.
- 03
Check a sample
Match its label and drawing revision to the quoted line.
- 04
Agree release
Record buyer approval, carton marks and document owners.
Who uses the brief

Aftermarket importers
Match references before adding a line.
Parts distributors
Specify kit contents and carton labels.
Fleet buyers
Group requests by platform and axle.
Repair networks
Separate press-in kits from hub units.
Catalog teams
Record fitment exceptions before publication.
Supplier quality
Agree sample checks before release.
Evidence matrix
Evidence before commitment
Supplier records
Match the quoted company, manufacturing site and part number to the drawing and commercial offer.
Sample check
Check bore, outside diameter and width against the agreed drawing. An illustrative 42 × 80 × 36 mm dimension record identifies only the envelope. Record the sample code, ABS encoder ring orientation and seal lip geometry separately.
Document scope
Separate a quality-system certificate’s site and scope from evidence covering a particular SKU and market.
Inspection brief
Define the lot, sample plan and reporting method. If the hub flange drawing specifies axial face runout, agree its datum and fixture separately from any radial runout check. Carry the supplier drawing’s limits into the inspection brief.
Release decision
Record whether the sample is approved, conditionally approved or held for unresolved differences.
Shipment checklist
Reconcile part numbers, carton counts and shipping marks against the packing list before handoff.
Buyer questions
Before you send the list
Is an OE reference enough to confirm fitment?
It starts the search. A supersession or production split can change the seal or encoder. Include the VIN or exact platform and build date, axle position, old-part markings and drawing if available.
When should a quote separate bearing and hub options?
Quote them separately when the platform supports both service scopes. A complete unit may reduce press and setup work. A serviceable bearing may retain reusable hardware, subject to the vehicle service procedure.
How are minimums and lead times confirmed?
Request them per supplier and SKU after scope review. For a stock offer, confirm the available quantity and its validity. For a custom kit, ask whether sample approval or packaging artwork starts the lead-time clock.
Can one request include several suppliers?
Yes. Compare offers per line and identify the consolidation owner. A single source simplifies release tracking. A split award broadens coverage and adds packaging and document checks at handoff.
