Raw-edge Cogged V-belt

  • Proven cost-effective design that is the preferred option on many applications.
  • Optimum flexibility provides greater heat dissipation which insures longer operational efficiency.
  • Variable spacing of cogs provides improved belt performance by reducing noise and tension decay.

Raw-edge Cogged Banded

  • Popular on trucks, agricultural units, heavy equipment, and other applications where large gasoline and diesel engines are used.
  • Cogged design provides an area for air circulation further reducing heat build-up and providing greater flexibility.
  • Laminated construction of the bottom fabric reduces noise in the drive that is inherently loud.


  • Combine the benefits of flat belt flexibility with the power transmission capability of the V-belt.
  • Proven reliability on drives with or without automatic tensioners.
  • Rubber compounds are formulated to reduce noise caused by humid conditions and worn pulleys.

Double-sided V-ribbed

  • Provides the ultimate in belt design for use on today's modern engines where space and weight are critical
  • Accessories can be driven from the top or bottom side of the belt enabling compact designs.
  • Top or backside ribs are capable of handling high load accessories.
