Sleeve Auto Bearing Specification Example for Aftermarket Retail: Premium Line

This is a worked specification for sleeve auto bearing in a premium line programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The premium line version exists because the duty cycle on aftermarket retail is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually packing that arrived crushed at the port.

Where this example applies

Programmes that run premium line most often specify this build for aftermarket retail. Related applications include construction equipment, city buses, trailer axles, racing teams, long-haul trucks.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 1.5 sampling on the finished lot.
  • Finish inspection under agreed lighting.
  • Carton drop test on the first lot of a new packing specification.

Questions buyers ask

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ISO/TS 16949-compliant build instead of a fresh interpretation.

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.

What happens if a lot fails inspection?

The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
