High strength synthetic cords resist shock load failure and low stretch properties assure uniform performance over the life of the belt. The compression section is a special rubber compound that assures smooth and even transfer of the load forces to the cords. Cogs are molded to precise engineering tolerances to improve flexibility and maintain cord support. Cog geometry provides a large area for air circulation to keep the belt cool and prevent damaging heat buildup in the cushion section. Rubber edges maintain positive no-slip contact with pulley grooves for reliable energy transfer.
