High strength synthetic cords resist shockload. Low stretch properties assure uniform performance over the life of the belt. Special rubber compound section assures smooth and even transfer of load forces to the cords. Cogs are molded to precise engineering tolerances to improve flexibility and maintain cord support. Provides a large area for air circulation keeping the belt cool while preventing heat build up. Rubber edges maintain positive, no-slip contact with pulley grooves for reliable energy transfer.
