Flat Wire Belt or Eye Link Belt: What Changes in Production?
Both are open, strong belts for food lines; they differ in how they support product and carry load. Our factory makes both to your old belt or drawing and confirms strip, link and rod sizes on the drawing you approve. See our flat wire belts and eye link belts.
Short answer
A flat wire belt has flat strips formed into a honeycomb, giving a large open area, easy cleaning and gentle support for light to medium loads. An eye link belt has wire links on cross rods, giving more strength for heavier loads and wide frying or cooking lines.
I am Sunny Ye, Global Sales Director at YIYI MESH BELT in Ningjin, Shandong, China. Our manufacturing experience dates back to 1998. We make both belts and match each to the product and the drive.
At a glance
| Product | Flat Wire / Honeycomb Belt and Eye Link Belt |
|---|---|
| Application | Baking, cooling, freezing, frying, washing |
| Key parameters to confirm | Open area, load, product size, rod and strip size, drive, cleaning |
| Buyer type | Food plants, bakeries, equipment makers |
| What to send for a quote | Product and size, load per metre, width, temperature and cleaning method |
How are the two belts built?
The structure explains the strengths of each belt.
A flat wire belt is made of flat strips bent into openings and held by cross rods, so it is light and very open. An eye link belt is made of wire eye links threaded on cross rods, so it is stronger across the width and carries heavier loads.
| Feature | Flat Wire Belt | Eye Link Belt |
|---|---|---|
| Structure | Flat strips in a honeycomb | Wire links on cross rods |
| Rod pitch | 12.7–50.8 mm | 25.4–76.2 mm |
| Rod Ø | 3–8 mm | 5–8 mm |
| Width | 200–4000 mm | 300–3000 mm |
| Edge | Washer welded, clinched or rod welded | Roller chain or reinforced plate |
When does a flat wire belt fit better?
Flat wire is the open, easy-to-clean choice.
A flat wire belt fits better for light to medium products that need air or water flow through the belt, such as baked goods, cooling and freezing, and lines that are cleaned often. The open honeycomb drains well and the smooth strips support product evenly.
For a deep-sea fishing equipment maker we built two electropolished SUS304 flat wire belts with 1.6 × 12.7 mm strip, bent by hand to avoid inner scratches, with matched 14-tooth sprockets.
When does an eye link belt fit better?
Eye link is the strength choice.
An eye link belt fits better for heavier products, wide belts, frying and cooking lines, and where reinforcing bars or a roller chain edge are needed. The cross rods and links share the load across the width, so the belt stays flat under weight.
For a new potato frying line we built eye link belts up to 2,582 mm wide with 5 mm rods at 50 mm pitch, reinforcing bars and a roller chain edge.
Which questions decide it?
Load and product size decide most cases.
Decide with four questions: how heavy is the load per metre, how small is the smallest product, how is the belt driven, and how often is it cleaned? Light, open and frequently washed points to flat wire; heavy, wide or chain-driven points to eye link.
- LoadPer metre of belt.
- ProductSmallest size that must not fall through.
- DriveSprockets, drums or chain edge.
- CleaningHow often, and with what.
When this is not the right choice
Flat wire is not right for heavy frying or cooking loads on wide belts; it can bow.
Eye link is not the natural choice when the product is very light and the line needs maximum open area and simple cleaning.
From our engineering experience
For a deep-sea fishing equipment maker we sent flat wire samples first, checked sprockets against the belt and let the customer inspect first articles at our factory. For a potato frying line we built reinforced eye link belts with matched sprockets.
My advice: send the heaviest and the smallest product you run. Those two decide the belt.
Evidence from our work
- Situation
- Two SUS304 flat wire belts, 600 and 800 mm wide, for fishing equipment.
- What we checked
- Strip 1.6 × 12.7 mm, rod 5 mm at 27.4 mm pitch, electropolished; 14-tooth sprockets checked against the belt.
- Why it matters
- An open, smooth belt suited a wet, salty process that is cleaned often.
- Result
- Shipped with 40 sprockets and 310 flight clip sets after a running video.
- Buyer lesson
- Choose flat wire for open, clean conveying; eye link for load.
FAQ
Which is easier to clean?
Flat wire usually, because of its large open area and smooth strips.
Which carries more load?
Eye link, especially with reinforcing bars and a chain edge.
Can both be electropolished?
Electropolishing is arranged with partners where specified; flat wire belts are often electropolished.
Can I change from one to the other?
Sometimes, if the drive and support suit the new belt. Send the conveyor details and we check.
Conclusion
Light, open and washed often: flat wire. Heavy, wide or chain-driven: eye link. Confirm with load, product size and the drive.
