Banded Belts are designed of finest quality material for oil and heat resistance and long lasting durability. Banded wrapped design used for pulsating loads and long center distances. Multiple V-belts in unit construction prevents material from getting in sheave grooves. Classical banded style for use with iron sheaves. By combining two belts using the common backing process, these Banded Belts greatly reduce the tendency for single belts, which when subjected to fluctuating load tensions may come off or turn over in multiple pulley drives.
