Overview
The Gates A51 Hi-Power II V-Belt (SKU: 9002-2051) is a classical A-section wrapped V-belt engineered for demanding industrial and agricultural power transmission applications. The wrapped classical section Hi-Power™ V-belt has a long reputation for reliability on agricultural and industrial applications. This belt combines proven design with advanced materials to maximize uptime and minimize downtime in conveyor systems, pumps, compressors, and other rotating equipment.
Key Features
- The arched top of the Hi-Power belt provides superior strength to prevent “dishing” and distortion of the tensile section.
- Vulcanized Flex-bonded tensile cords provide superior resistance to tensile and flexing forces, fatigue and shock loads.
- Featuring a composite, multi-purpose construction, Gates® Hi-Power™ II Belts resist oil, heat, ozone, sunlight, weather, and aging.
- The EPDM belt material is engineered to combat self-igniting, meaning the belt won’t catch fire from heat build-up, even with severe slippage.
- All sizes meet Gates UNISET tolerances, and can be installed without matching.
- Static conductive (ISO 1813) and can be used in conditions described in the Directive 2014/34/EU- ATEX.
