What Changes When Our Factory Builds a Heavy-Duty Eye Link Belt?
Heavy-duty eye link belts fail when they are built like light ones. Our factory sets link, rod and pitch from your old belt or drawing and confirms them on the drawing you approve before production. See our eye link belts.
Short answer
Choose a heavy-duty eye link belt by sizing the cross rod and rod pitch to the load, choosing the eye-link wire, adding reinforcing bars across wide belts, specifying a roller chain or reinforced plate edge for the drive, and matching sprockets. Each choice is recorded on the approved drawing.
I am Sunny Ye, Global Sales Director at YIYI MESH BELT in Ningjin, Shandong, China. Our manufacturing experience dates back to 1998. We build eye link belts up to 3,000 mm wide, many with reinforcing bars and roller chain edges.
At a glance
| Product | Eye Link Belt with sprockets |
|---|---|
| Application | Frying, cooking, freezing, heavy-duty conveying |
| Key parameters to confirm | Rod Ø and pitch, eye-link wire, reinforcement, edge, width, sprockets |
| Buyer type | Food plants, equipment makers |
| What to send for a quote | Load per metre, width, temperature, drive and a photo of the old belt |
How do you size the rod and pitch?
The cross rod carries the load across the width.
Size the cross rod and rod pitch from the load per metre and the belt width: heavier loads and wider belts need a thicker rod or a closer pitch. We use 5, 6 or 8 mm rods at 25.4 to 76.2 mm pitch.
| Dimension | Range |
|---|---|
| Eye-link pitch | 3.6 / 5 / 6 / 8 / 10.5 / 12 mm |
| Rod pitch | 25.4 / 50 / 50.8 / 76.2 mm or custom |
| Eye-link wire | 1.6 / 2 / 2.5 mm |
| Cross rod | 5 / 6 / 8 mm or custom |
| Width | 300–3000 mm |
When do you need reinforcing bars?
Wide belts need strength across the span.
Add reinforcing bars across the belt when the width or the load would let the mesh bow between rods or supports, which is common on wide frying and cooking belts. The bars share the load across the span and keep the surface flat under product.
For a new potato frying line we added 2.5 × 12 mm reinforcing bars to belts up to 2,582 mm wide.
Which edge should a heavy-duty belt have?
The edge carries the pull.
A heavy-duty eye link belt usually needs a roller chain edge, which carries the drive through sprockets and keeps the mesh from taking the pull; a reinforced plate edge suits lighter drive loads. The chain pitch, rollers and sprockets are confirmed with the belt on one drawing.
Sprockets are machined by partners to our drawing and checked against the belt by us before shipment.
How are sprockets matched?
Heavy belts are hard on sprockets.
Match sprockets by specifying tooth count, pitch, bore and width on the same drawing as the belt, and check them on the belt before shipment. On a new line, every sprocket set is machined to that drawing; on a replacement, worn sprockets should be replaced with the belt.
For the frying line, five sprocket sets were machined to the same drawings as the belts and checked on the belt.
When this is not the right choice
A light eye link specification is not right for a wide frying belt; it bows and wears early.
Ordering belt and sprockets from separate drawings is not right on a heavy-duty line.
From our engineering experience
For a new potato frying line we built four eye link belts from customer drawings, 325 to 2,582 mm wide, with 5 mm rods at 50 mm pitch, reinforcing bars and a roller chain edge, plus five sprocket sets.
My advice: give us the load per metre and the width. The rod, the reinforcement and the edge follow from them.
Evidence from our work
- Situation
- Four SUS304 eye link belts and five sprocket sets for a new frying line.
- What we checked
- Eye-link pitch 6.5 mm, rod pitch 50 mm, rods 5 mm, eye-link wire 2.5 mm, reinforcing bars 2.5 × 12 mm, chain edge 50 mm pitch washer welded.
- Why it matters
- Wide frying belts need strength across the span and a chain edge for the drive.
- Result
- Sample approved, mass production, sprockets checked on the belt, measured photos before shipment.
- Buyer lesson
- Specify rod, reinforcement, edge and sprockets together for heavy duty.
FAQ
How wide can an eye link belt be?
300 to 3,000 mm, or custom.
Can you add reinforcing bars?
Yes, across the belt, on the approved drawing.
Do you supply sprockets?
Yes, specified on the same drawing and checked against the belt.
Which materials are available?
Mild steel, SUS304 and SUS316, chosen for the process.
Conclusion
Size rods to the load, reinforce wide belts, drive with a chain edge and match sprockets on one drawing. That is a heavy-duty eye link belt.
