Unlike standard single-sided V-belts, the AA79's hexagonal profile allows it to transmit power from both sides of the belt, making it the correct choice for serpentine drives and reverse-bend drive systems where one or more idler pulleys contact the back of the belt. It is commonly used in agricultural machinery, lawn and garden equipment, industrial drives, and OEM multi-pulley systems.\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e  \u003cli\u003eBelt Section: AA (Double Angle \/ Hex)\u003c\/li\u003e  \u003cli\u003eTop Width: 1\/2\" (12.7 mm)\u003c\/li\u003e  \u003cli\u003eBelt Depth: 0.42\" (10.67 mm)\u003c\/li\u003e  \u003cli\u003eOutside Circumference: 81\" (approx. 82.4\" measured OC per industry standard)\u003c\/li\u003e  \u003cli\u003eProfile: Hexagonal - dual-sided power transmission\u003c\/li\u003e  \u003cli\u003eCompatible Pulleys: Standard A-section sheaves\/pulleys\u003c\/li\u003e  \u003cli\u003eConforms to ARPM Standard IP-21\u003c\/li\u003e  \u003cli\u003eOil resistant, heat resistant, and static dissipating construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eApplications\u003c\/h4\u003e\u003cp\u003eAA-section Double V-Belts are used on drives with one or more reverse bends, and wherever power must be transmitted to pulleys on both the inner and outer belt surfaces.
