Car Bearing Specification Example for Municipal Fleets: Lightweight Version
Car Bearing Specification Example for Municipal Fleets: Lightweight Version
This is a worked specification for car bearing in a lightweight version 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 lightweight version version exists because the duty cycle on municipal fleets 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.
Example specification
| Item | Car Bearing |
|---|---|
| Application | Municipal Fleets |
| Version | Lightweight Version |
| Base material | Powder Coated Steel |
| Controlled dimensions | 6 key dimensions, recorded per lot |
| Tolerance band | ±0.05 mm |
| Finish | as machined |
| MOQ | 200 pieces per specification |
| Sampling | 7 working days, 3 days per revision |
| Compliance | SAE J431 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Powder Coated Steel, 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
- rubber vulcanisation
- die casting
- sintering
- laser cutting
- anodising
Where this example applies
Programmes that run lightweight version most often specify this build for municipal fleets. Related applications include delivery vans, construction equipment, passenger cars, three-wheelers, 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
What testing is included?
Standard lots ship with dimensional and hardness reports. SAE J431 documentation is issued with the shipment when your market requires it.
What is the minimum order quantity?
The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
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 200 pieces per line.
Ask for the current catalogue and the specification sheet for this line.
