Planetary Axle Specification Example for Off-Road Bikes: OEM Replacement
Planetary Axle Specification Example for Off-Road Bikes: OEM Replacement
This is a worked specification for planetary axle 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 off-road bikes 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.
Example specification
| Item | Planetary Axle |
|---|---|
| Application | Off-Road Bikes |
| Version | OEM Replacement |
| Base material | Nylon 66 |
| Controlled dimensions | 6 key dimensions, recorded per lot |
| Tolerance band | ±0.1 mm |
| Finish | powder coated |
| MOQ | 3,000 pieces per specification |
| Sampling | 14 working days, 5 days per revision |
| Compliance | RoHS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Nylon 66, 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
- CNC machining
- robot welding
- powder coating
- cold forging
- laser cutting
- injection moulding
Where this example applies
Programmes that run oem replacement most often specify this build for off-road bikes. Related applications include agricultural trailers, export programmes, construction equipment, trailer axles, dealership service.
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 long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
What is the minimum order quantity?
The standard MOQ is 3000 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 3000 pieces per line.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the RoHS-compliant build instead of a fresh interpretation.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
