Gates B143 Hi-Power II V-Belt B Section 146 Inch

The Gates B143 Hi-Power II V-Belt is a heavy-duty industrial and agricultural power transmission belt designed for reliable performance in demanding applications. This B-section classical V-belt features a 146-inch outside circumference with a 21/32-inch top width and 13/32-inch height, making it suitable for a wide range of equipment drives.

Advanced Construction Features:

• Flex-Weave Cover: Patented single-layer fabric construction provides extended protection against oil, dirt, and heat while making the belt suitable for clutching applications
• Flex-Bonded Cords: Proprietary polyester cord construction strongly bonds to the belt body for uniform load distribution and superior resistance to bending stress, fatigue, and shock loads without cord deterioration
• Gates Curves Design: Optimized belt cross-section with concave sidewalls and rounded corners provides proper cord support and full contact with pulley grooves for uniform loading, minimal wear, and extended service life
• EPDM Rubber Compound: Resists weathering, oils, water, solvents, ozone, and sunlight while preventing self-ignition even under severe slippage conditions
