The wrapped classical section Hi-Power™ V-belt has a long reputation for reliability on agricultural and industrial applications. The arched top of the Hi-Power belt provides superior strength to prevent "dishing" and distortion of the tensile section. The cords are properly aligned, each of them carrying its full share of the load.

Arched top, concave sidewalls and rounded corners provide uniform tensile loading and uniform pulley sidewall contact for excellent belt service life and reduced pulley wear.

Vulcanized Flex-bonded tensile cords provide superior resistance to tensile and flexing forces, fatigue and shock loads.

Flex-Weave™ oil and heat resistant cover protects the belt core from the toughest environments.

All sizes meet Gates V80™ system matching tolerances.

Meets ARPM/RMA IP-3-2 oil and heat resistant standards and IP-3-3 static conductivity requirements. REACH and RoHS 2 compliant.
