Axle Shaft Specification Example for Agricultural Trailers: OEM Replacement
Axle Shaft Specification Example for Agricultural Trailers: OEM Replacement
This is a worked specification for axle shaft in a oem replacement 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 oem replacement version exists because the duty cycle on agricultural trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.
Example specification
| Item | Axle Shaft |
|---|---|
| Application | Agricultural Trailers |
| Version | OEM Replacement |
| Base material | ABS Plastic |
| Controlled dimensions | 4 key dimensions, recorded per lot |
| Tolerance band | ±0.05 mm |
| Finish | as machined |
| MOQ | 500 pieces per specification |
| Sampling | 10 working days, 5 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 — ABS Plastic, 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
- laser cutting
- anodising
- CNC machining
- robot welding
- ultrasonic cleaning
- cold forging
Where this example applies
Programmes that run oem replacement most often specify this build for agricultural trailers. Related applications include light trucks, boat trailers, fleet maintenance, city buses, assembly programmes.
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SAE J431-compliant build instead of a fresh interpretation.
What is the minimum order quantity?
The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
Ask for the current catalogue and the specification sheet for this line.
