Axle Shaft Specification Example for Off-Road Bikes: Folding Type
Axle Shaft Specification Example for Off-Road Bikes: Folding Type
This is a worked specification for axle shaft in a folding type 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 folding type 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 supplier who changed material without saying so.
Example specification
| Item | Axle Shaft |
|---|---|
| Application | Off-Road Bikes |
| Version | Folding Type |
| Base material | Powder Coated Steel |
| Controlled dimensions | 3 key dimensions, recorded per lot |
| Tolerance band | ±0.5 mm |
| Finish | powder coated |
| MOQ | 200 pieces per specification |
| Sampling | 10 working days, 5 days per revision |
| Compliance | ISO 9001 |
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
- robot welding
- heat treatment
- CNC machining
- shot blasting
- precision stamping
- injection moulding
Where this example applies
Programmes that run folding type most often specify this build for off-road bikes. Related applications include racing teams, export programmes, municipal fleets, construction equipment, aftermarket retail.
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
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
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.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
What testing is included?
Standard lots ship with dimensional and hardness reports. ISO 9001 documentation is issued with the shipment when your market requires it.
