Gates B81 Hi-Power II Classic V-Belt 84 Inch

The Gates B81 Hi-Power II V-Belt is a premium classical section belt engineered for reliable performance in agricultural and industrial applications. This B-section belt features an 84-inch outside circumference (81-inch inside length) with a 21/32-inch (0.66-inch) top width and 13/32-inch thickness, making it ideal for a wide range of power transmission needs.

Advanced Construction Features:

• EPDM Compound: Engineered to resist oil, heat, ozone, sunlight, weather, and aging while preventing self-ignition even under severe slippage conditions
• Flex-Bonded Cords: Vulcanized tensile cords are strongly bonded to the belt body for equal load distribution and superior resistance to bending stress, fatigue, and shock loads
• Flex-Weave Cover: Oil and heat-resistant woven fabric cover with built-in static conductivity protects the belt core from harsh operating environments
• Arched Top Design: Provides superior strength to prevent dishing and distortion of the tensile section while ensuring proper cord alignment
• Gates Curves: Engineered for proper cord support and full sheave-groove contact, delivering uniform loading, reduced wear, and extended belt life

Performance Standards:

• Meets ARPM/RMA IP-3-2 oil and heat-resistant standards
• Meets ARPM/RMA IP-3-3 static conductivity requirements
• Compatible with Gates V80 system matching tolerances
• Operating temperature range: -22°F to +140°F (-30°C to +60°C)
• REACH and RoHS 2 compliant

This belt is suitable for all industrial applications including v-flat drives and is recommended for use with Multi-Duty sheaves. The machined belt edges ensure even sheave groove contact for smoother operation and reduced slip.
