Ribbed Belt (Poly V-Belt) is a new kind of transmission belt and widely applied to automotive, textile, chemical, light industry, oil and mining etc. Ribbed Belt have advantages of flat belt and V-Belt.

Good mechanical performance,

Thin and lighter body, smaller dimension,

High tensile strength,

Smooth transmission and smaller slipping difference

Better flexibility and high efficiency

Long life

Power saving.

Automotive Ribbed Belt are mainly PK series and PJ series.

It is predominantly the materials used which differentiate the CR and EPDM ribbed belts.

The CR ribbed belt has both heat and cold resistance capabilities. Its flexing, aging and ozone ageing resistance are generally better than those of unsaturated rubber. It also offers better oil and solvent resistance and chemical stability. It can endure high levels of transverse and belt pitch pressure and has comparatively reduced after-strained deformation.

EPDM ribbed belts offer much better aging resistance, especially ozone, weather and heat resistance. In addition, this products electric insulation properties, chemical corrosion resistance and impact elasticity, especially at low temperatures, are superior to the CR ribbed belt.
