Champion HR7-8 VRV7-8 HRV7-12 VR7-8 V-Belt

The Champion HR7-8 / VRV7-8 / HRV7-12 / VR7-8 V-Belt (83" OD) is an industrial V-belt that powers air compressor drive systems by transferring torque from the motor to the compressor pump. Commonly installed in Champion reciprocating compressor packages where belt-driven operation is required, it serves in manufacturing and workshop environments for mechanical power transmission in belt-driven air systems. Key specs include Outside Length: 83 inches, Belt Section: B-section / industrial V-belt equivalent (model dependent), Construction: Rubber V-belt with reinforced tensile cords, and Cord Material: Polyester or aramid (application dependent). The belt is designed for continuous and intermittent compressor loading, offering heat resistance and flexibility for cyclic compressor operation, and is compatible with Champion compressor sheave systems (HR/VR series). Typical applications include air compressors, industrial compressor units, and workshop systems in industrial facilities. Common replacements include Gates B83, Continental B83 Industrial V-Belt, and PIX B83 Compressor Belt.
