Polymer Rollers  

Polymer rollers, also known as idler rollers or conveyor rollers, are cylindrical bars that run along and underneath a conveyor belt to support the weight and impact of materials being transported. At Vagheshwar Industries, we manufacture high-quality polymer rollers for a variety of industrial applications.


Our polymer rollers consist of a machined polymer tube or solid bar mounted on sealed precision bearings. Bearings are protected by non-contact rubber seals and metal end caps. Roller tubes can be machined to tight tolerances for balanced operation.

Key benefits:

  • Smooth and quiet rotation
  • Minimal maintenance
  • Long service life
  • Withstands vibration, shock loads
  • Customizable to application

    Roller Properties

    Polymer rollers have excellent properties that make them ideal for conveyor applications:

    • High impact strength: Withstand repeated impacts from materials without cracking or breaking
    • Abrasion resistance: Resist wear from abrasive materials like rocks, ore, etc.
    • Low coefficient of friction: Reduces drive power and belt wear
    • Noise reduction: Quieter operation compared to steel rollers
    • Corrosion resistance: Performs well in wet, chemical-laden environments
    • Electrical insulation: Non-conductive for safety around electrical equipment

    Here are some suggested specifications for the polymer rollers:


      • Diameter: 50mm to 400mm
      • Length: Customizable, up to 2000mm
      • Materials: UHMWPE, Nylon, Acetal, PTFE
      • Hardness:
        • UHMWPE: 60-65 Shore D
        • Nylon: 40-90 Shore D
        • Acetal: 80-90 Shore D
        • PTFE: 50-60 Shore D
      • Surface Finish: Machined, Ra 0.4μm or better
      • Bearings: Sealed precision ball bearings or tapered roller bearings
      • Temperature Range:
        • UHMWPE: -40°C to 80°C
        • Nylon: -40°C to 100°C
        • Acetal: -40°C to 90°C
        • PTFE: -40°C to 250°C
      • Load Capacity: Up to 2000 kg per roller
      • Noise Reduction: Up to 50% lower noise versus steel rollers
      • UV Resistance: Excellent, suitable for outdoor use

          FAQs – Carrying Rollers

          What materials are the rollers made from?

          We offer a range of polymer materials like UHMWPE, nylon, acetal, and PTFE. Material is selected based on application requirements.

          What bearing types are used?

          Sealed precision ball bearings or tapered roller bearings depending on load and speed requirements.

          What is the service life of polymer rollers?

          With proper maintenance, service life can exceed 5 years even in demanding applications. Far longer than rubber lagged steel rollers.

          Can polymer rollers be used outdoors?

          Yes, polymer rollers have excellent UV resistance and perform well outdoors.
