Gates B71 Hi-Power II V-Belt B Section 74 Inch

The Gates B71 Hi-Power II V-Belt is a heavy-duty, multipurpose power transmission belt designed for demanding industrial and agricultural applications. This B-section belt features a 74-inch outside circumference (71-inch inside circumference) and is engineered with advanced EPDM rubber construction for exceptional durability and performance.

Key Features:

• Superior Material Construction: EPDM (ethylene propylene diene monomer) rubber compound resists oil, heat, ozone, sunlight, weathering, and aging
• Self-Ignition Protection: Engineered material prevents belt from catching fire due to heat buildup, even during severe slippage conditions
• Flex-Bonded Cords: Tensile cords are strongly bonded to the belt body for equal load distribution and superior resistance to bending stress without cord deterioration
• Flex-Weave Cover: Patented woven fabric cover provides extended protection to the belt core from oil, dirt, and heat while ensuring longer service life
• Gates Curves Design: Concave sidewalls provide proper cord support and full contact with sheave grooves for uniform loading, reduced wear, and increased belt life
• V80 Matching System: Precision manufacturing ensures all B71 belts can be used in matched sets without additional matching requirements
