On a chain driven belt, the chain does the pulling and the mesh does the carrying. Choose them together, with the sprocket.
Choose the chain for a chain driven belt as part of a belt, chain and sprocket system. Confirm chain pitch, chain model, material, how the rods attach to the chain, the sprocket, and the belt pitch and width. A chain model number does not by itself fix pitch, material or sprocket.
We are YIYI Mesh Belt (Ningjin Yiyi Mesh Belt Co., Ltd.), a manufacturer of engineered metal conveyor belts for equipment manufacturers, professional distributors and industrial end users, based in Ningjin, Shandong, China. Our manufacturing experience dates back to 1998; the current company was established in 2008. We make Chain Driven Belts in SUS304, SUS316 and carbon steel. I am Sunny Ye. The older version of this article listed general industrial chain types, including plastic chains we do not use. This version covers the chains that matter for a chain driven metal belt.

Why Is a Chain Driven Belt Reviewed as a System?
In a chain driven belt, the side chains carry the drive force and the mesh carries the product. The rods connect them. If chain pitch, rod spacing and sprocket do not match, the belt runs rough, jumps sprockets or wears unevenly. So the belt, the chain and the sprocket are reviewed together.
| Part | Role | Key data |
|---|---|---|
| Mesh | Carries the product | Belt or spiral pitch, rod pitch, wire |
| Rods | Connect mesh and chains | Rod diameter, spacing, retention |
| Chains | Carry the drive force | Chain pitch, model, material |
| Sprockets | Drive the chains | Tooth count, pitch, bore, wear |
Rod spacing has to fit the chain pitch, because rods are fixed to chain links. That relationship is set on the drawing. A belt with the right mesh but the wrong chain cannot be fixed on site.
Our Chain Driven Belt references cover belt or spiral pitch 3–20 mm, rod pitch 4–20 mm, wire 1–3 mm and widths from 300 to 5,000 mm or custom. These are reference ranges, not free combinations.
Sunny's view: When someone sends me a chain model and asks for a quote, my first reply is: please send a photo of the sprocket.
How Do You Identify Chain Pitch and Model?
Chain pitch is the distance between pin centres. Measure it over several links and divide, because wear stretches chains. Compare it with the references, then check roller diameter, plate height and width to identify the model. A model number such as C2052 helps, but pitch, material and attachment still have to be confirmed.
| Chain pitch | Typical models in our references |
|---|---|
| 12.7 mm | #40 |
| 15.875 mm | #50 |
| 25.4 mm | C2042 |
| 31.75 mm | C2052 |
| 38.1 mm | C2062 |
| 50.8 mm | C2082 |
| 63.5 mm | C2102 |
These are common pairings under standard roller chain numbering. Your chain may use a different variant, an extended pin or a special attachment, so we confirm it from photos, measurements or a sample.
How to measure
- Measure across ten pitches and divide by ten.
- Measure roller diameter and inner width.
- Photograph the chain from the side and from above, with a ruler.
- Photograph how the rods attach to the chain.
Sunny's view: A worn chain can measure several millimetres long over ten pitches. That is why we never quote from one link.
Which Chain Material Fits Your Line?
Stainless steel chains in SUS304 or SUS316 suit food lines, wet conditions and washing. Carbon steel chains suit dry industrial lines where corrosion is not a concern. The chain material should match the belt and the environment, and the sprocket material should be reviewed with it so the pair wears evenly.
| Condition | Chain material to review |
|---|---|
| Food processing, washing, wet lines | SUS304 or SUS316 |
| Salt, brine or chlorinated cleaning | SUS316 |
| Dry industrial conveying | Carbon steel may be suitable |
| High temperature | Specific review with the equipment data |
Core metal belt manufacturing and quality control are managed in-house, while selected chains and sprockets are sourced under our project specifications and finished-product quality requirements. Either way, the chain is checked with the belt in final assembly.
For grade choice, read SUS304 or SUS316 for a conveyor belt.
Chain lubrication also depends on the line. In food areas, follow the equipment builder's instructions and use lubricants approved for that environment, or run stainless chains dry where the design allows it.
Sunny's view: Mixing a stainless belt with a carbon steel chain in a wet line is a common way to get rust stains on product. Match them.
How Do Rods Attach to the Chain?
Rods pass through hollow pins or attachment holes in the chain and are held by welded washers, cotter pins or other retention. The attachment decides how easily the belt can be repaired and how it behaves at the sprocket. Confirm it from photos of the old belt or the drawing.
- Washer welded: a washer is welded on the rod end outside the chain. Strong and simple.
- Cotter pin: easier to dismantle for repair.
- Special attachments: extended pins, side plates or guards for particular machines.
Rod diameter and the hole in the chain must match with the right clearance. Too tight and the belt cannot flex at the sprocket; too loose and the mesh moves and wears.
Side guards, flights and lane dividers can be added where the line needs them, reviewed on the drawing.
On a replacement, copy the retention method of the old belt unless there is a reason to change it. A change from washer welded to cotter pin, or the reverse, alters the width over the chains and the clearance at the frame.
Sunny's view: Send a close-up of one rod end at the chain. That single photo tells me the attachment, the rod size and the retention.
Why Must the Sprocket Be Reviewed With the Chain?
The sprocket must match the chain pitch and roller, and its teeth must be in good condition. A worn sprocket on a new chain causes noise, jumping and fast wear. Send tooth count, bore and side photos of the teeth with every chain driven belt inquiry, and plan to replace worn sprockets with the belt.
- Tooth count and pitch diameter
- Bore, keyway and hub
- Tooth wear: hooked or polished teeth mean replacement
- Material, matched to the chain
- Alignment across both sides of the belt
Both sprockets on a shaft should drive both chains equally. If one side runs ahead, the belt skews and the rods bend. We supply Drive Sprockets and Related Conveyor Components matched to the belt and chain on a project basis, and sprocket matching is part of our checks where applicable.
Read why a chain driven belt jumps on sprockets (yiyimeshbelts.com).
Sunny's view: When a chain driven belt jumps, look at the sprocket teeth before you look at the belt.
What Should You Send to Replace a Chain Driven Belt?
Send the belt type and width, the mesh pitch and wire, the chain pitch and model, how rods attach to the chain, the sprocket details and photos, the machine and application, and a drawing if you have one. A short sample of belt with chain is the strongest evidence for a formal replacement.
Checklist
- Belt type and total width; width between chains
- Mesh: belt or spiral pitch, rod pitch, wire and rod diameters
- Chain: pitch over ten links, model if known, material
- Attachment: photo of a rod end at the chain, retention type
- Sprockets: tooth count, bore, photos of the teeth
- Machine and application: product, load, temperature, cleaning
- Drawing or sample, if available
Photos and basic dimensions support a preliminary quote. For a formal order we prepare a drawing for your approval, then run trial production and a first article before mass production, and inspect every belt before packing.
For more on measuring, read what parameters you need to replace a metal wire belt.
Sunny's view: Lay a tape measure along the chain and photograph ten links. That photo answers the pitch question in one look.
When This Is Not the Right Approach
A chain driven belt is not needed for every metal belt line. Where the load is light and the line straight, a friction-driven or sprocket-driven belt without side chains, such as a Flat Wire / Honeycomb Belt or a Balanced Weave Belt, may be simpler. For heavy plates or a solid surface, a Chain Plate / Plate Link Belt may fit better.
Plastic chains and plastic modular belts are not part of our range.
From Our Engineering Experience
Most chain driven belt inquiries we receive are replacements, and the most common missing item is sprocket data. The second is how the rods attach to the chain. With those two, the rest of the review is usually straightforward.
In final inspection we check structure, chain relationship, sprocket matching where applicable, dimensions and final assembly, so the belt arrives as one system, not as mesh and chain to be matched on site.
FAQ
What chain pitches do you offer?
Our references are 12.7, 15.875, 25.4, 31.75, 38.1, 50.8 and 63.5 mm. The chain for your belt is confirmed on the drawing.
Does the chain model fix the pitch and material?
No. A model number helps identify the chain, but pitch, material, attachment and sprocket are still confirmed.
Which materials are available?
SUS304, SUS316 and carbon steel, chosen by the environment and matched to the sprocket.
How do I measure chain pitch on a worn chain?
Measure across ten pitches and divide by ten. One link hides wear.
Should I replace sprockets with the belt?
If the teeth are hooked or polished, yes. Worn sprockets damage a new chain quickly.
Conclusion
Choose the chain with the belt and the sprocket: pitch, model, material and attachment, confirmed on a drawing. Send sprocket photos with every inquiry.
Replacing a chain driven belt?
Send photos of the chain, a rod end at the chain, the sprocket teeth, and the belt width. We review belt, chain and sprocket together.
