AC Fan Motor Specification Example for Off-Road Bikes: Standard Replacement
AC Fan Motor Specification Example for Off-Road Bikes: Standard Replacement
This is a worked specification for ac fan motor in a standard 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 standard 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 | AC Fan Motor |
|---|---|
| Application | Off-Road Bikes |
| Version | Standard Replacement |
| Base material | Titanium Alloy |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.1 mm |
| Finish | powder coated |
| MOQ | 2,000 pieces per specification |
| Sampling | 7 working days, 3 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 — Titanium Alloy, 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
- surface grinding
- ultrasonic cleaning
- precision stamping
- anodising
- gravity casting
Where this example applies
Programmes that run standard replacement most often specify this build for off-road bikes. Related applications include off-road bikes, municipal fleets, long-haul trucks, racing teams, agricultural trailers.
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
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.
What testing is included?
Standard lots ship with dimensional and hardness reports. SAE J431 documentation is issued with the shipment when your market requires it.
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 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
