Nylon Conveyor Belts (NN Conveyor Belts)
Hongkun supplies nylon conveyor belts (NN conveyor belts) with nylon fabric reinforcement and rubber covers for bulk material handling. Nylon yarns run in both fabric directions. The fabric carcass carries belt tension, while rubber covers protect the carrying and pulley sides.
Choose the NN grade, ply count and cover construction for the actual conveyor duty. Send an existing belt marking or your conveyor requirements for a quotation.
Nylon Fabric Conveyor Belt Construction
An NN conveyor belt has a nylon fabric carcass inside a rubber belt. This nylon fabric conveyor belt belongs to the textile-reinforced rubber belt family.
- Nylon warp runs along the belt length.
- Nylon weft runs across the belt width.
- Rubber skim layers bond the fabric plies.
- Top and bottom rubber covers protect the carcass.
The nylon conveyor belt described here is a rubber-covered belt for bulk conveying. Open mesh belts for filtering, drying or food processing fall outside this product scope.
NN Conveyor Belt Specification: Model and Ply Strength
Use the NN model and ply count together when reading a belt specification. The table shows strength values in N/mm for each listed construction.

| NN model | 2 plies | 3 plies | 4 plies | 5 plies | 6 plies |
|---|---|---|---|---|---|
| NN-100 | 200 | 300 | 400 | 500 | 600 |
| NN-150 | 300 | 450 | 600 | 750 | 900 |
| NN-200 | 400 | 600 | 800 | 1000 | 1200 |
| NN-250 | 500 | 750 | 1000 | 1250 | 1500 |

| NN-400 | Not listed | Not listed | 1600 | 2000 | 2400 |

Confirm the finished belt rating, dimensions and test requirements before ordering. The model alone does not define cover thickness, belt width or roll length.
How to Specify an NN200 Conveyor Belt
NN200 identifies a fabric grade. The finished belt specification also needs the ply count, dimensions and rubber covers. The supplied reference lists 800 N/mm for the four-ply NN-200 construction.
For an NN200 conveyor belt inquiry, provide:
- The full old belt marking, if available.
- Fabric grade and number of plies.
- Finished belt length, width and total thickness.
- Top and bottom rubber cover thickness.
- Required finished belt rating and test method.
This helps separate the fabric grade from the complete belt construction. If the old marking is missing, send clear photos of the belt surface and cut edge.
NN and EP Conveyor Belts
NN uses nylon warp and nylon weft. EP uses polyester warp and nylon weft. Review belt stretch and take-up travel before changing between the two constructions.
For replacement projects, confirm working tension, pulley diameter, loading conditions and available take-up travel. Matching the belt width alone does not establish replacement suitability.
Compare EP conveyor belts for the polyester/nylon construction. Use the fabric conveyor belts overview to compare textile carcass types.
Application and Replacement Information
Select the NN construction against the conveyed material and conveyor design. For cement, coke, metallurgy or steel plant inquiries, identify the actual material and operating conditions.
Provide the details that apply to your conveyor:
- Material name, particle size, lump size and moisture.
- Loading arrangement, drop height and impact conditions.
- Conveyor length, incline and belt speed.
- Pulley diameters, working tension and take-up travel.
- Old belt marking, cut-edge photos and damage photos.
Hongkun reviews the carcass and rubber cover requirements together for the proposed duty.
Nylon Conveyor Belt Price and Manufacturer Inquiry
A nylon conveyor belt price depends on the specified construction and order details. Send the dimensions, NN grade, ply count, cover thickness and quantity for a project-specific quotation.
When comparing nylon conveyor belt manufacturers, use the same specification for each quotation. Ask suppliers to identify the following.
- Offered carcass construction and finished belt rating.
- Rubber cover grade and thickness.
- Agreed test methods and inspection documents.
- Roll arrangement, delivery terms and destination.

Frequently Asked Questions
Is a nylon rubber conveyor belt the same as an NN belt?
The terms can describe the same product when the belt has an NN fabric carcass and rubber covers. Confirm the complete construction because “nylon belt” can also describe other belt types.
Can I replace an EP belt with an NN conveyor belt?
Have the replacement reviewed against the conveyor design. Confirm working tension, pulley diameter, operating elongation and take-up travel before changing the carcass.
Does NN200 specify the complete conveyor belt?
No. NN200 identifies a fabric grade. Include the number of plies, finished dimensions and cover thickness to define the required construction.
What information is needed when the old belt has no marking?
Send belt length, width and total thickness with surface and cut-edge photos. Include the material and any conveyor or pulley information available to your team.
