V-BELTS
– High strength synthetic cords resist
shockload failure. Their 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 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 build up in the cushion
section.
™ Rubber
edges maintain positive,
no-slip contact with pulley grooves
for reliable energy transfer.
