Overview
The Gates 3VX710 Super HC PowerBand is a molded notch, banded cogged V-belt engineered for demanding industrial power transmission applications. This 4-row banded configuration combines flex-bonded polyester reinforced cords with PowerBand® tie-band construction, enabling multiple belts to function as a single unit with even load distribution. The Gates 3VX710 features a 71-inch outside circumference and 3VX narrow-wedge section profile, making it ideal for compact, high-performance drives.
Key Features
- 4-Row PowerBand® Construction: Banded tie band joins multiple belts for lateral rigidity, preventing belt whip, turn-over, and slippage on multiple-belt drives.
- Molded Notch Design: Notches reduce bending stress and improve flexibility around small-diameter sheaves while maintaining load-carrying capacity.
- EPDM Rubber Compound: Ethylene propylene diene monomer construction provides superior resistance to weathering, oils, water, and selected solvents.
- Flex-Bonded Cord Technology: Polyester reinforcement cords are strongly bonded to belt body, ensuring equal load distribution and absorption of bending stress without cord deterioration.
- Extended Temperature Range: Operates reliably from -60°F to +250°F, resistant to cracking and exceeding RMA and ISO standards.
- V80® Matching System: Precisely manufactured tolerances exceed Rubber Manufacturers Association (RMA) and International Standards Organization (ISO) requirements, ensuring consistent performance across multi-belt installations.
