  • Heat & Oil Resistant

    CR / NR / EPDM compounds engineered for reliable performance in hot, oily engine compartments.

  • High Strength Cord

    Polyester / Aramid / Fiberglass tensile cords provide low stretch and stable power transmission.

  • Wear-Resistant Cover

    Fabric-reinforced cover resists abrasion and ensures consistent friction on pulleys.

Typical Applications

Our V-belts deliver dependable friction-drive power transmission across a wide range of industries. From HVAC and agriculture to pumps, fans, compressors, and generators, they offer smooth operation, shock absorption, and cost-effective maintenance.

  • HVAC & Refrigeration Compressors

    Ribbed belts deliver smooth, vibration-free power to commercial HVAC and refrigeration compressors, ensuring consistent cooling performance with minimal noise.

  • Automotive Front End Accessory Drive

    Poly V belts power multiple engine accessories—alternator, water pump, A/C compressor, and power steering—from a single serpentine layout, saving space and simplifying maintenance.
