V-Ribbed Belts

V-Ribbed Belts combine the benefits of flat belt flexibility with a v-belt's power transmission capability.

V-Ribbed Belts provide 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.
  • Rubber compounds are formulated to reduce noise caused by humid conditions and worn pulleys.

Proven reliability on drives with or without automatic tensioners.

Optimum flexibility provides greater heat dissipation which insures longer operational efficiency for one belt drive systems.

Top Fabric (V-Ribbed only)
Flexible, bias cut fabric is impregnated with oil and heat resistant rubber to eliminate wear and cracking.

Insulation Rubber
Cords are encloses in an oil and heat resistant rubber compound with strong adhesive qualities for maximum cord support and long life.

Tensile Cords
High tensile strength aramid or pre-stretched polyester cords insure high horsepower capacity and constant belt tension on spring tension systems and locked center drives.

Rib Rubber
Rib rubber is reinforced with fiber chips and heat resistant rubber compound for wear resistance and reduced noise.


Raw-Edge Cogged & Raw-Edge Multi-Ply
A proven, cost effective design that is the preferred option on many applications.

Popular on trucks, agricultural units, heavy equipment and other applications where large gasoline and diesel engines are used.

Optimum flexibility provides greater heat dissipation which insures longer operational efficiency. Cogged design provides area for air circulation further heat build-up and provides greater flexibility.

Variable spacing of cogs provides improved belt performance by reducing noise and tension decay.

Laminated construction of the bottom fabric reduces noise in the drive that is inherently loud.

Still maintains a strong replacement market for older cars produced before v-ribbed belts were introduced.

Top Fabric
Strong, wear resistant bias cut fabric designed for protection without loss of flexibility.

High tensile strength, pre-stretched polyester cords for reduced stretching and constant tension.

Compression Rubber
Reinforced with fiber chips to provide high coefficient of friction, wear resistance and greater flexibility. Insures a smooth and even transfer of load forces to the cords.

Bottom Fabric
Crack resistant, highly flexible fabric is impregnated with an oil and heat resistant rubber compound. Laminated construction ensures a strong bond and reduced noise.

Rubber Sides
Eliminates slip and maintains a positive contact with the pulley grooves.
