Hub centric ring sample on a measurement surface

Hub centric rings

Record the wheel center bore and the vehicle hub pilot separately. A nominal 66.6 mm to 57.1 mm ring pairs a 66.6 mm wheel center bore with a 57.1 mm hub pilot. Confirm register depth and chamfer against both parts so the ring can seat without interfering with the wheel mounting face.

05 / Questions before quoting

Fitment and order boundaries

What are hub centric rings?

A ring can locate an aftermarket wheel with a larger center bore on the vehicle hub pilot. A ring leaves bolt pattern, offset, seat geometry and load rating unchanged. Check these against the wheel and vehicle specifications.

Stock rings or a custom profile?

A stocked pair of diameters simplifies replenishment if depth and chamfer also match. A custom profile gives more control over those interfaces and requires agreement on drawing revision, sample approval and the supplier's minimum order.

One supplier or a split order?

A single supplier can simplify carton labels and lot records. Splitting rings, fasteners and weights can improve assortment coverage and adds SKU-level checks before consolidation.

Can a document follow a similar part?

Match the issuer, supplier site, part identification, revision and target market to the quoted item. A similar-looking sample or a quality-management certificate leaves the product test scope unresolved.
