MWIN is a professional manufacturer of industrial rubber conveyor belts and bulk material handling solutions based in Qingdao, China. Our Nylon Canvas Core Rubber Conveyor Belt (NN belt) is a multi-ply fabric-reinforced conveyor belt, with the carcass constructed from high-strength impregnated nylon (polyamide) canvas, laminated and bonded together, then covered top and bottom with premium compound rubber. Manufactured by calendering, shaping and vulcanization, it is engineered for medium-to-long distance, high-load and high-speed bulk material transportation in heavy industries.
Suitable for lump, granular and powder non-corrosive bulk materials: Mining & coal, cement & building materials, ports & bulk terminals, metallurgy, quarry & stone crushing, grain storage, fertilizer plants, sand and aggregate production lines.
High tensile strength with thin belt body, allowing smaller pulley diameters and reducing bending resistance.
Excellent impact absorption & superior troughability, reduces material spillage.
Strong interlayer bonding and flex fatigue resistance for extended service life.
Low residual elongation, minimizes frequent tension adjustment during running.
Multiple rubber cover grades available: ordinary wear-resistant, high abrasion resistant, oil-resistant, acid & alkali resistant, cold-resistant and flame-retardant

High tensile strength with thin belt body Nylon canvas provides superior tensile performance while keeping the belt relatively thin, which reduces bending resistance and allows smaller pulley diameters.
Excellent impact resistance & troughability Great elasticity to absorb shock from falling lump materials. It forms a stable trough shape on troughed idlers, minimizing material spillage and boosting conveying efficiency.
Strong interlayer bonding & superb flex fatigue resistance Advanced vulcanization process ensures tight bonding between canvas plies and rubber covers. The belt withstands repeated bending cycles and extends service life.
Low residual elongation Elongation under working load is controlled within a low range, reducing frequent tension adjustment during operation.
Multiple customized cover options available We supply ordinary, high-abrasion, oil-resistant, acid & alkali resistant, cold-resistant and flame-retardant grades according to working conditions.
Q1: How soon can we get a reply after we send you an inquiry?
A: The reply will be made within 2 hours after receiving the inquiry.
Q2: Are you a direct manufacturer or a trading company?
A: We have our own factory and international trade department, handling both production and sales directly.
Q3: What products can you provide?
A: We produce ST cord conveyor belts, sensor conveyor belts, pip conveyor belts, anti-tear conveyor belts, EPDM conveyor belts, high temperature resistant conveyor belts, heat resistant conveyor belts, fire resistant conveyor belts, EP conveyor belts, NN conveyor belts, SW fabric conveyor belts, cotton conveyor belts, chevron conveyor belts, rough top conveyor belts, oil resistant conveyor belts, chemical resistant conveyor belts, flat transmission belts, and rubber V belts.
Q4: What application fields are your products mainly involved in?
A: Primarily used for transportation tasks in metallurgy, chemical, cement, coking, steel and other industrial sectors.
Q5: What is the best way to store conveyor belts?
A: Conveyor belts should be stored in a cool, dry, and dark place, away from direct sunlight, rain, and chemicals. They should be kept in a rolled position (not folded) to prevent cracking or damage to the core. Avoid placing heavy objects on top of the rolls.
Q6: How does your company guarantee product quality?
A: We maintain complete physical and chemical testing equipment with a dedicated quality management team. All properties are controlled from raw material analysis through semi-finished products to finished product testing.
Q7: Can you customize the size and specifications of the belts?
A:Yes. We offer customized solutions based on your requirements. You can specify the width, length, cover thickness, color, and rubber properties(such as heat-resistant, oil-resistant, or flame-retardant) to match your specific conveyor system.
Q8: How to deliver goods to customers?
A: We primarily ship by sea from Qingdao port for convenience. For urgent shipments, air transport is available through the nearby international airport.
