➊ High strength synthetic cords resist shockload failure.

Their low stretch properties assure uniform performance
over the life of the belt.

➋ The compression section is a special rubber compound

that assures smooth and even transfer of load forces to
the cords.

➌ 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 build up in the
cushion section.

➍ Rubber edges maintain positive, no-slip contact with

pulley grooves for reliable energy transfer.
