Ball Auto Bearing Specification Example for Light Trucks: Folding Type

This is a worked specification for ball auto bearing in a folding type 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 folding type version exists because the duty cycle on light trucks is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — EPDM Rubber, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • cold forging
  • heat treatment
  • anodising
  • precision stamping
  • die casting
  • gravity casting

Where this example applies

Programmes that run folding type most often specify this build for light trucks. Related applications include trailer axles, three-wheelers, light trucks, scooter fleets, agricultural trailers.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 2.5 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

How is packing specified?

Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.

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.

Can the specification be held on file?

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

What testing is included?

Standard lots ship with dimensional and hardness reports. REACH documentation is issued with the shipment when your market requires it.

Tell us the model, the fitment and the quantity and we will hold a production slot for you.
