Send a bore pair, a flange profile or an OE reference. Add the quantity by SKU and delivery information so the desk can compare the same supply scope.
Enter your specificationsFor a ring, give wheel center bore as OD and hub pilot as ID. A 66.6 mm OD and 57.1 mm ID illustrate the format. Add the chamfer and seating depth. For a weight, replace the bore pair with the rim flange profile and mass increments.
Check a listed size against the mating parts first. If a standard ring cannot seat on the intended geometry, request a drawing, tolerance and sample for a custom ring. Compare the supplier’s MOQ and tooling terms per SKU. A standard size can simplify repeat orders when the interface and pack size fit. A custom size can address a different seating depth, but add an approval sample and a separate tooling line to the comparison.
Provide the drawing revision and the gauge or inspection method. For a hub, add OE cross reference, hub flange geometry and ABS encoder ring orientation. Ask the supplier to identify the SKU and lot on the sample record. For a ring sample, have the inspector check the OD and ID at the drawing datums, record the readings in mm and compare them with the specified tolerance. Add any axial gap at the mating face as an open item before approval.
