FRK POWER automotive ribbed belts are mainly PK series and PJ series. FRK POWER ribbed belts are produced using special material, formulation and techniques so as to provide heat, oil, abrasion and aging resistance and such advantages as lower noise levels and longer life.
The standard pitch and common angle and belt thickness of the ribbed belt are as below:
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 aging 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 resistant.
