Sleeve Auto Bearing Specification Example for Assembly Programmes: Vented Design

This is a worked specification for sleeve auto bearing in a vented design 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 vented design version exists because the duty cycle on assembly programmes 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 — Titanium Alloy, 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

  • laser cutting
  • precision stamping
  • shot blasting
  • anodising
  • electroplating
  • injection moulding

Where this example applies

Programmes that run vented design most often specify this build for assembly programmes. Related applications include fleet maintenance, boat trailers, agricultural trailers, export programmes, trailer axles.

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

What testing is included?

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

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 is the minimum order quantity?

The standard MOQ is 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

Can you match an existing sample?

Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
