Features of Yujiang automotive
ribbed belt:
 Yujiang
automotive ribbed belts are mainly PK series and
PJ series. Yujiang 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 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.
