Axle Shaft Specification Example for Off-Road Bikes: Long Life Version
Axle Shaft Specification Example for Off-Road Bikes: Long Life Version
This is a worked specification for axle shaft in a long life 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 long life version 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 inconsistent hardness between lots.
Example specification
| Item | Axle Shaft |
|---|---|
| Application | Off-Road Bikes |
| Version | Long Life Version |
| Base material | Tempered Glass |
| Controlled dimensions | 3 key dimensions, recorded per lot |
| Tolerance band | ±0.5 mm |
| Finish | zinc plated |
| MOQ | 1,000 pieces per specification |
| Sampling | 10 working days, 5 days per revision |
| Compliance | CCC |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Tempered Glass, 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
- surface grinding
- robot welding
- assembly line testing
- gravity casting
- electroplating
Where this example applies
Programmes that run long life version most often specify this build for off-road bikes. Related applications include construction equipment, workshop replacements, passenger cars, dealership service, camper conversions.
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
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.
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the CCC-compliant build instead of a fresh interpretation.
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.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
