Automotive Piston Pin Specification Example for Off-Road Bikes: Touring Version
Automotive Piston Pin Specification Example for Off-Road Bikes: Touring Version
This is a worked specification for automotive piston pin in a touring 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 touring 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 premature wear on the first batch.
Example specification
| Item | Automotive Piston Pin |
|---|---|
| Application | Off-Road Bikes |
| Version | Touring Version |
| Base material | Aluminium Alloy |
| Controlled dimensions | 3 key dimensions, recorded per lot |

| Finish | zinc plated |
| MOQ | 2,000 pieces per specification |
| Sampling | 7 working days, 3 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 — Aluminium 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
- injection moulding
- anodising
- precision stamping
- shot blasting
- cold forging
- powder coating
Where this example applies
Programmes that run touring version most often specify this build for off-road bikes. Related applications include courier fleets, racing teams, utility trailers, fleet maintenance, light trucks.
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 is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
What testing is included?
Standard lots ship with dimensional and hardness reports. RoHS 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 RoHS-compliant build instead of a fresh interpretation.
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.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
