Roller

Rollers are crucial components of belt conveyors, serving to support the conveyor belt and the materials being transported. They help reduce the running resistance of the conveyor belt and ensure that the belt’s sag does not exceed specified limits, thereby guaranteeing smooth operation. The roller structure consists of a roller body, bearings, seals, and other parts. According to their application, rollers can be categorized into types such as trough-shaped, parallel, and self-aligning. They are widely used in industries including mining, ports, and power plants.

  • Technical Parameters
  • The idler rollers feature high wear resistance, a low coefficient of friction, and are unlikely to damage conveyor belts. They boast excellent self-lubricating properties, eliminating the need for lubrication and ensuring smooth operation even under harsh conditions without getting jammed. They are antistatic, flame-retardant, resistant to aging, and highly tolerant to corrosion by acids, alkalis, and organic solvents. These rollers can withstand repeated impacts and vibrations. The operating temperature range is from -40°C to 90°C.

    It features excellent mechanical performance, lightweight design, easy installation, and maintenance-free operation; it also boasts stable operation and a long service life. Our factory also produces a wide range of conveyor belt-related products, fully capable of meeting your needs.

Compared with other types of conveyor belts, nylon conveyor belts feature high strength, excellent impact resistance, superior abrasion resistance, minimal deformation, good flexibility, and robust splices. Nylon conveyor belts can be made using rubber compounds such as SBR, NBR, and EPDM, and they offer high tensile strength as well as multi-layer fabric conveyors with outstanding resistance to abrasion, oil, heat, and wear. These belts can be manufactured either as flat nylon belts or as patterned nylon belts. They are available in a variety of specialized formulations, including fire-resistant, cold-resistant, wear-resistant, heat-resistant, acid- and alkali-resistant, oil-resistant, and anti-static types.
