Sleeve Auto Bearing Specification Example for Delivery Vans: Premium Line
Sleeve Auto Bearing Specification Example for Delivery Vans: 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 delivery vans is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.

Example specification
| Item | Sleeve Auto Bearing |
|---|---|

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
- anodising
- gravity casting
- ultrasonic cleaning
- shot blasting
- robot welding
- assembly line testing
Where this example applies
Programmes that run premium line most often specify this build for delivery vans. Related applications include aftermarket retail, camper conversions, assembly programmes, emergency vehicles, light trucks.
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
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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
What testing is included?
Standard lots ship with dimensional and hardness reports. RoHS documentation is issued with the shipment when your market requires it.
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.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
