Sleeve Auto Bearing Specification Example for Delivery Vans: Two-Piece Construction
Sleeve Auto Bearing Specification Example for Delivery Vans: Two-Piece Construction
This is a worked specification for sleeve auto bearing in a two-piece construction 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 two-piece construction version exists because the duty cycle on delivery vans is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a fitment that looked right on paper and failed on the bench.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Sintered Metal, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- cold forging
- assembly line testing
- die casting
- rubber vulcanisation
- injection moulding
- powder coating
Where this example applies
Programmes that run two-piece construction most often specify this build for delivery vans. Related applications include long-haul trucks, export programmes, aftermarket retail, city buses, emergency vehicles.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 2000 pieces per line.
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 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 part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
