B-Series V-Belts

Classic B-Series V-Belts have a 0.66" top-width, 0.41" thickness, and a 40° angle to them. Additionally, B V-belts are one of the oldest styles of V-Belts in the industry. Because of their long-term success and economic operation, they are also one of the most widely used belt series in the industry. The premium B-series v-belts we supply are manufactured under ISO 9001 specifications, are oil and heat resistant, and directly interchange with other brands. They are constructed of a natural rubber compound with polyester cords and use cotton with a polyester blend for a high durability cover. B series belts are used in most general industrial applications along with Heating, ventilation, and air conditioning (HVAC) equipment, lawn and garden equipment, and agricultural equipment. We also stock a complete line of high-power Kevlar v-belts along with the accompanying v-belt pulleys/ sheaves.
