Wheel Drive Axles Specification Example for Scooter Fleets: Waterproof Version
Wheel Drive Axles Specification Example for Scooter Fleets: Waterproof Version
This is a worked specification for wheel drive axles in a waterproof 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 waterproof version version exists because the duty cycle on scooter fleets is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually documentation that arrived after the container shipped.
Example specification
| Item | Wheel Drive Axles |
|---|---|
| Application | Scooter Fleets |
| Version | Waterproof Version |
| Base material | Cast Iron |
| Controlled dimensions | 5 key dimensions, recorded per lot |

| Finish | powder coated |
| MOQ | 500 pieces per specification |
| Sampling | 7 working days, 3 days per revision |
| Compliance | TUV |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Cast Iron, 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
- rubber vulcanisation
- heat treatment
- ultrasonic cleaning
- precision stamping
- sintering
- robot welding
Where this example applies
Programmes that run waterproof version most often specify this build for scooter fleets. Related applications include workshop replacements, delivery vans, construction equipment, scooter fleets, courier fleets.
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 7 working days, and each revision round adds about 3 days once you have seen the first piece.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the TUV-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
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.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
