How Do You Keep a Belt Specification Record for Future Reorders?
Reordering a belt from memory or an old invoice line restarts the whole specification. A one-page record makes the next order a copy.
Short answer
Keep a belt specification record with the approved drawing and its revision, measured photos of the delivered belt, the material, the drive and sprocket data, the machine it runs in, and any changes made since. With it, a reorder is built to the same drawing, not specified again.
I am Sunny Ye, Global Sales Director at YIYI MESH BELT in Ningjin, Shandong. We have made metal conveyor belts since 1998 and run 280 units of production equipment, including 9 automatic welding robots. Some of our customers have reordered the same belts for more than ten years, and this is what makes that simple.
At a glance
| Product | Any metal conveyor belt and its sprockets |
|---|---|
| Application | Repeat orders, spare belts, multi-site plants |
| Key parameters to confirm | Drawing number and revision, dimensions, material, finish, drive, machine, changes |
| Buyer type | Maintenance managers, purchasing teams, OEMs, distributors |
| What to send for a quote | Your record or the previous order reference; we match it to our approved drawing |
What belongs in a belt specification record?
The record is short, but every line in it is something you would otherwise have to measure again.
A belt specification record holds the approved drawing number and revision, the key dimensions, the material and finish, the edge and drive details, the machine and position where the belt runs, and the delivery date. Add measured photos of the delivered belt so anyone can check the numbers later.
| Field | Example |
|---|---|
| Drawing and revision | Our drawing number, rev. B, signed date |
| Dimensions | Width, length, pitch, wire and rod |
| Material and finish | SUS304, pickled and cleaned |
| Edge and drive | Roller chain edge, 13-tooth sprockets, bore 35 mm |
| Machine | Line and position where it runs |
| Delivered | Date, quantity, spare parts supplied |
Who should hold the record: you or the supplier?
Both. Two copies are what make a reorder safe.
Both sides should hold it. We keep the approved drawing and order records for every belt we make, so a repeat order is built to the same drawing. You should keep your own copy too, because people change on both sides.
When a repeat order arrives, our team pulls the approved drawing of the previous order, and the production notice is reviewed by engineering before anything is made.
If your copy and ours disagree, that is a useful signal. Something changed, a machine, a product or a part, and it should be confirmed before production.
How do you record changes between orders?
A belt rarely stays identical for ten years, and that is fine if every change is written down.
Record every change as a new drawing revision with the reason and the date, for example a new spiral pitch, a different edge or new sprockets. The next order then follows the latest approved revision, and nobody has to guess whether an older drawing is still valid.
A freezer builder in South America re-ordered a spiral belt in 2026 with a revised spiral pitch. The construction stayed the same; the pitch changed on the drawing, and the first article was measured again before production continued.
What should you send when you reorder?
With a record, a reorder email can be three lines.
When you reorder, send the drawing number and revision, the quantity and any change since the last order. If you are not sure the drawing is still right, add one photo of the running belt with a ruler. We confirm the drawing with you before production starts.

When this is not the right choice
A record is not a reason to skip a check when something has changed. If the product, drive or temperature is different, review the drawing before reordering.
An old invoice line is not a specification record. Invoices describe what was sold, not how the belt was built.
From our engineering experience
A tunnel-freezer equipment maker in Europe has ordered eye link belts and sprockets from us for 13 years. Each repeat order is built to the approved drawings of the previous one, and the production notice is reviewed by engineering every time.
A distributor in Southern Africa re-ordered a chain plate belt in 2021 built to the drawing from 2020. My advice: keep the drawing, the photos and one page of notes, and your next order takes minutes, not weeks.
Evidence from our work
- Situation
- An equipment maker re-orders eye link belts and matched sprockets for its tunnel freezers.
- What we checked
- The 2026 order: four widths from 300 to 1,500 mm, 25.4 and 50 mm belt pitch, 6 mm eye-link pitch, 29 sprockets with 12 and 13 teeth, all to the previous approved drawings.
- Why it matters
- Approved drawings on file turn every repeat order into a confirmation instead of a new specification.
- Result
- Belts and sprockets were pickled, cleaned, dried and shipped in export cases, built to the same drawings as earlier orders.
- Buyer lesson
- Keep the approved drawing and photos; they are worth more than any catalogue number.
FAQ
Do you keep drawings of past orders?
Yes. We keep approved drawings and order records, so a repeat order is built to the same drawing.
Can you rebuild a belt from an order ten years old?
If the approved drawing is on file, yes. We confirm with you that nothing in the machine has changed.
What if I lost my drawing?
Send the previous order reference or photos of the belt; we check our records and confirm the drawing with you.
Should sprockets be in the record?
Yes. Tooth count, bore and thickness belong in the record with the belt.
Can you send me a copy of the approved drawing?
Yes. Ask for the drawing of your order and keep it with your maintenance records.
Conclusion
Keep the approved drawing, its revision, measured photos and drive data. Then every reorder is a confirmation, not a new specification.
