The procurement desk
About CEMB procurement coordination
CEMB is an independent China sourcing and procurement service for wheel-end parts. The desk coordinates requests and evidence between buyers and suppliers.
What a buyer can approve
Every quote should identify the part, the conditions of supply and the evidence a buyer needs before releasing an order.
We keep fitment gaps such as center bore, rim flange or OE cross reference separate from commercial questions. Suppliers issue part drawings and their own evidence. Buyers approve the application and any engineering changes. A system certificate describes the named site and scope. For a product claim, request the document tied to the offered SKU, revision and target market.
Examples of review points
These illustrations identify what to document during a sample review.
Buyer worksheets
Use a worksheet to record the dimensions and the source of each value. For a ring, an illustrative 66.6 mm wheel bore and 57.1 mm hub pilot still require a drawing and seat-depth check. For a replacement hub, attach the OE cross reference, hub flange dimensions, and ABS encoder ring orientation to the sample approval record. When a standard bore pair is suitable, record the supplier drawing and compare pack sizes before ordering. A ring with a different axial depth calls for a custom drawing, with tooling cost and sample approval listed separately. Record the ring material, gauge readings and acceptance limits so a later revision can be reviewed against the same criteria.
Bring a part reference to the desk
Send a drawing revision, an OE number or a marked sample photograph description.
