Start here: which light duty belt do you need?
Most people arrive knowing the job, not the construction. Find your situation and follow the link to the matching belts.
| If your situation is… | Look at | Why |
|---|---|---|
| The belt touches food | Food belting | FDA-approved white, green and tan covers, 35 to 150 PIW |
| Product is hot, wet or sticky | Hot stock and water | Silicone covers rated to 500 °F, or a bare cotton duck top |
| You are moving cartons, totes or parcels | Package handling | Covered tops for grip, several with bare backs that slide easily on a slider bed |
| General conveying, nothing special about the product | General purpose | Nitrile-covered and friction-surface belts, 36 to 225 PIW |
| The belt drives something rather than carries it | Transmission | Friction surface on both sides, 90 to 280 PIW |
| You want the lightest, most flexible belt | Solid woven cotton | No rubber cover at all: a single woven cotton carcass, 45 to 110 PIW |
| Product sticks to the belt | Silicone covers or the PTFE (Teflon) food belt | Silicone releases hot, tacky product; PTFE gives a hard, slick, non-stick surface |
| Product slides back on an incline | Incline belting | Roughtop, wedgegrip and ribbed tops that grip cartons and bags |
| You need a PVC belt | PVC belting | A different construction, with its own page |
| Material is sharp, abrasive or dropped from a height | Heavy duty belting | Light duty belts are not built for impact or bulk-material abrasion |
What light duty belting is, and where it stops
Light duty versus heavy duty
Light duty belting is fabric-ply belting built to carry product : thin covers or none at all, a flexible carcass that bends around small pulleys, and tension ratings from 35 to 280 PIW. It suits steady loads such as boxes, bags, produce, packaged food and finished parts.
Heavy duty belting is built to survive material : thicker rubber covers to absorb impact and abrasion, and ratings from 150 to 600 PIW. The line between them is rarely about the weight of the product. It is about impact, abrasion and tension. If lumps drop onto the belt, or the material is sharp, you want heavy duty belting.
Light duty versus PVC
The belts on this page are fabric-ply constructions: layers of woven fabric bonded with rubber, usually with a rubber cover or friction surface on each face. That is what a name like "3-ply nitrile COS" describes. PVC belting is a PVC cover on an interwoven polyester carcass, and has its own page: PVC conveyor belting.
How PIW works on a light duty belt
PIW is pounds per inch of width: the working tension one inch of belt width is rated to carry. A 3-ply 90 PIW belt run 24" wide is rated for about 2,160 lb of working tension across the belt, not 90.
On light duty belting, PIW depends on the fabric as well as the number of plies, which is why a 2-ply and a 3-ply belt can carry similar ratings. When you replace a belt, match PIW and thickness first and ply count second. See What is PIW? for more, and the conveyor belt calculator to work out belt length.

Light duty belting FAQ
What does "light duty" mean, and when do I need heavy duty?
Light duty belting is fabric-ply belting rated about 35 to 280 PIW, with thin covers or none at all, built to carry product rather than survive impact.
Move up to heavy duty when material drops onto the belt from a height, when it is sharp or abrasive (aggregate, scrap, ore), when you need thick covers to absorb wear, or when the drive needs more tension than a light duty belt is rated for. For boxes, bags, produce, packaged food or finished parts, light duty is almost always the right family.
Is light duty belting the same as lightweight belting?
In everyday use, yes. Most people searching for lightweight belting or a light conveyor belt mean thin, flexible belting for carrying product rather than bulk material. Some suppliers use "lightweight" for plastic (thermoplastic) belts. If you are not sure what you are replacing, send us the old belt's name or a photo and we will identify it.
Do you sell PVC belting?
Yes, on its own page: PVC conveyor belting. PVC belts have a PVC cover on an interwoven polyester carcass, rather than rubber on fabric plies.
What makes a belt FDA approved, and when do I need one?
An FDA-approved belt has a cover made from compounds approved for contact with food. Our food belts use white, green or tan nitrile, white RMV rubber, butyl or PTFE (Teflon), from 35 to 150 PIW, and our solid woven cotton belts are FDA approved too.
You need one wherever the belt touches food, or where an inspector or customer audit requires food-contact materials. If your line is also USDA-inspected, confirm the belt meets the rules for your product.
What do COS, FS, FBS and "bare" mean?
They describe each face of the belt. COS is Cover One Side: rubber on top, a thin friction surface underneath. FS is a friction surface: a thin rubber skim instead of a thick cover. FBS is friction on both sides. Bare means the fabric is exposed on that face, which slides more easily on a slider bed. So "1/16 X FS" means a 1/16" cover on top and a friction surface underneath.
I need a non-stick belt surface. What are my options?
For hot, tacky product, a silicone cover releases best: our hot stock and water family has red and white silicone belts at 90 and 120 PIW, rated to 500 °F. For a hard, slick, non-stick surface on a food line, our 3-ply PTFE (Teflon) food belt is the option.
If the problem is drag on a slider bed rather than product sticking, a bare-back belt is usually the answer. Several of our package handling belts have bare backs for that reason.
What is solid woven cotton belting, and when should I choose it?
Solid woven cotton is cotton woven into a single carcass, with no rubber at all. It is light, flexible and FDA approved, and suits food and baking lines and slider beds that do not need the abrasion or oil resistance of a rubber cover. Ours runs 45 to 110 PIW, 2 to 4 plies.
What is the difference between transmission and package handling belting?
Transmission belts have friction surfaces on both sides (SBR, 3 to 8 plies, 90 to 280 PIW) and are built to drive or move against pulleys, slider beds and roller beds. Package handling belts have a cover on top for grip on cartons and totes, often with a bare back for slider beds.
Can you cut a belt to length and make it endless?
Yes. Every belt is cut to the width and length you order. We can also install mechanical lacing, splice it endless (vulcanized or glued), and add cleats, sidewalls or V-guides. Finishing is quoted to order; tell us your application requirements.
Can I order online?
Every light duty belt is listed in our online store with its full specs. Choose your width, enter the length, add it to the cart and check out to request a quote, and we will come back with pricing and delivery.
Can you match a belt from an OEM part number?
Often, yes. Many OEM replacement belts are a standard construction cut to an OEM size. Send the part number, or a photo of the old belt with its width, length, ply count and thickness, and we will identify the construction and quote a replacement.
Not sure which belt you need?
Send the application, the width and length, and a photo of the old belt if you have one. We will come back with a recommendation, not just a price.
