Buyer applications

CEMB sourcing by buyer program

Specify the application first. A mixed service assortment, a tire replenishment list and an axle-specific bearing program each need different comparison fields.

Purchase briefs by buyer type

Distributor assortments

A mixed ring assortment can contain the same outer diameter with several hub pilot sizes. Confirm each bore pair and axial depth and compare the drawing to both mating surfaces. Ask for size markings on inner packs so receiving can distinguish visually similar SKUs.

Workshop replenishment

A service network ordering clip-on weights by mass alone can receive a clip that seats differently on a steel or alloy rim. Send a flange cross section and the required weight increments, then agree how sample retention and seating will be inspected.

Fleet wheel and tire programs

For a fleet size list, separate rim diameter, rim width and load rating from tire load index and speed rating. Compare tread pattern, tread depth, duty cycle and destination by SKU so a split shipment preserves the planned mix.

Hub and bearing replacements

For a replacement program, decide by platform whether an integrated hub unit or a serviceable bearing kit fits the repair method. Check hub flange geometry, ABS encoder ring orientation, seal lip, bearing preload requirements and OE cross reference.

Trade-offs to resolve before a purchase

Illustrative · standard ring vs. custom geometry

For an aftermarket wheel and a known vehicle, take the 66.6 mm and 57.1 mm dimensions as a sizing example only. A standard ring is a candidate when the bore pair, material and seating depth match. Request a custom drawing when the chamfer or depth differs, and check the tolerance and gauge method on an approval sample before ordering.

Illustrative · integrated hub vs. bearing kit

A fleet may want to stock one unit per axle reference. Compare the integrated assembly, which packages flange and encoder together, with a serviceable bearing kit on a platform that supports it. Review who controls bearing preload and seal orientation and verify the wheel speed sensor signal under the vehicle maker’s prescribed procedure.

Illustrative · rolling resistance vs. grip

A regional fleet comparing tire offers can start with an example size such as 225/45R18 and a load index of 95 only as separate fields. Compare actual offered tires using the same rating basis and operating conditions. Request the report’s pressure, load and test method before comparing rolling resistance or grip results.
