Specification intake
Turn the buyer's hub pilot, center bore and rim flange measurements into a revisioned line sheet. Flag unknowns such as seat profile or clip clearance for the supplier reply.
From drawing to handoff
Eibach sourcing services
Send an existing drawing or a short list of unresolved dimensions. We turn the brief into comparable China supplier requests and coordinate the evidence needed for a buyer decision.
What the coordination covers
Quotation comparison
Ask each supplier to price the same quantities and packing assumptions. Record tooling ownership, minimum per SKU, named Incoterm location and the lead-time trigger in separate columns.
Sample and inspection coordination
Request a sample identifier and a measurement record for the drawing revision. On hub kits, record the OE cross reference and the hub flange or ABS encoder ring configuration on the same record. Give the inspector acceptance points for dimensions, fit and label checks, including radial runout and lateral runout when the buyer specifies the assembly, datum and measurement method.
Shipment document checklist
Reconcile quantities, box labels and supplier lot references against the packing list. Keep consolidation and export coordination separate from carrier booking and customs clearance responsibilities.
Decisions to settle before sampling
When can two quotes share a comparison row?
When they refer to the same part revision, finish, pack count and delivery basis. If one quote excludes a go/no-go gauge or proposes different tolerance limits, log that exception next to the price.
Can one supplier cover the entire line list?
A single source simplifies drawing revisions and carton reconciliation. Multiple sources can cover more rim profiles, but the buyer needs common inspection criteria and a lot-level packing record to combine the orders.
Who approves a sample or confirms a standard?
The buyer sets acceptance criteria and releases the sample. The supplier or relevant test body provides supporting records, which we index by issuer, revision, part number and target market.
Illustrative line item
From a nominal size to a comparable brief
Initial request
“Quote 66.6 to 57.1 hub centric rings.”
The request gives nominal diameters, leaving the wheel-side lead-in, hub-side seating depth, material and order split open.
Comparison-ready request
“Quote 66.6 mm wheel bore × 57.1 mm hub pilot rings against the attached drawing revision. State your tolerances and verify the proposed section against the mating parts.”
Show the same count per pack and list any dimensional departure next to the unit quote.
