M Section Poly-V Belts:


M Section Poly-V Belts are high-performance power transmission belts designed to offer smooth and efficient operation in various industrial and automotive applications. They are characterized by multiple longitudinal ribs running along their length, which engage with corresponding grooves on pulleys to deliver superior grip and power transfer.


Design & Construction

  • Ribbed Profile: The M-section configuration consists of a series of small, parallel ribs that enhance flexibility and frictional engagement with pulleys.
  • 9.4mm Pitch: The M section has the largest rib pitch of all Poly-V belt profiles, measuring 9.4mm between adjacent ribs, making it suitable for high-torque applications.
  • Rubber Composition: Made from high-quality rubber compounds such as EPDM or neoprene for excellent resistance to wear, heat, and oil.
  • Reinforcement Cords: Embedded polyester or aramid fiber cords enhance tensile strength and minimize elongation under load.
  • Back Cover: Some variants include a fabric backing or reinforcement to increase durability and resistance to cracking.

Key Features

  • High Efficiency – Reduced slippage and increased surface contact improve energy transfer.
  • Largest Pitch Poly-V Belt – The 9.4mm rib pitch allows for higher torque transmission.
  • Compact Design – Allows for smaller pulley diameters, reducing overall system size.
  • Quiet Operation – Minimal vibration and noise due to uniform load distribution.
  • Long Service Life – Durable materials and low-stretch construction increase belt longevity.
  • Heat & Oil Resistance – Suitable for demanding environments with exposure to high temperatures and lubricants.
  • Minimal Maintenance – Requires less retensioning compared to conventional V-belts.

Applications

  • Automotive: Alternators, air conditioning compressors, power steering, and accessory drives.
  • Industrial Machinery: Compressors, pumps, fans, and conveyors.
  • Fitness Equipment: Treadmills and exercise machines requiring smooth motion.
  • Household Appliances: Washing machines, dryers, and vacuum cleaners.

Specifications

  • Profile Type: M-section
  • Rib Pitch: 9.4mm (largest among Poly-V belts)
  • Width Variability: Available in different rib counts to suit various power requirements
  • Operating Temperature: -25°C to +100°C (varies by material composition)

Advantages Over Conventional V-Belts

  • Increased flexibility allows for higher-speed operations.
  • Can operate on serpentine drives without tensioners.
  • Reduced heat buildup enhances performance and efficiency.
  • Uniform load distribution minimizes belt wear.

M Section Poly-V Belts are an optimal solution for applications requiring reliable, high-efficiency power transmission in a compact and durable design. Their superior grip, largest rib pitch (9.4mm), resistance to wear, and low maintenance requirements make them a preferred choice in multiple industries.
