Browning Classical V-Belts are designed to deliver maximum performance and service life. Classical belts feature single wrap design, which provides greater flexibility when using small diameter sheaves. Classical single wrap V-Belts also have less fabric overlap, which reduces center distance variation and vibration. For energy conscious users, our AX/BX molded notched/cogged V-Belts are up to 3% more efficient than the wrapped designs. Additionally, they are offered in all standard sizes.
