Gates 12/A77 Hi-Power II PowerBand V-Belt

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.

EXCELLENT PERFORMANCE WITH PULSATING LOADS.

Hi-Power II PowerBand belts are especially developed for high-power drives subjected to pulsating loads. The PowerBand technology consists of several V-belts joined together by a permanent, high strength tie band, thus providing more powerful, tougher performance than the sum of the belts measured separately.

Features and Benefits

• Flex-Bonded Cords are strongly bonded to the body of the belt resulting in equal load distribution and the absorption of bending stress without cord deterioration.
• The Flex-Weave Cover is a patented fabric construction for longer cover life, providing extended protection to the belt core from oil, dirt and heat.
• Concave sidewalls provide proper cord support and full contact with the sheave-groove for equal loading and uniform wear.
• Gates Curves provide full contact with pulley grooves for uniform loading of cords, uniform wear and increased belt life.
• The Tie Band assures high lateral rigidity, guiding the belt in a straight line and preventing it from coming off the drive.
• Static conductive (ISO 1813) and can as such be used in the conditions described in the Directive 2014/34/EU-ATEX.
• Savings in drive space and weight due to high transmission efficiency.
• High stability and smooth running on the toughest drives.
• Temperature Range: -30°C to +60°C (-22°F to +140°F).
• Important design economies possible.
• Available on demand in Matched sets.
• Better resistance to vibrations.
• REACH and RoHS 2 compliant.

EQUIPPED FOR YOUR OPERATING ENVIRONMENT.

Featuring a composite, multi-purpose construction, Gates Hi-Power II PowerBand belts resist oil and heat, ozone, sunlight, weather, and aging. We've even engineered the EPDM belt material to combat self-igniting, meaning your belt won't catch fire from heat build-up, even with severe slippage.
