A-Series V-Belts
Classic A-Series V-Belts are one of the oldest styles of V-Belts in the industry. Because of their long-term success and economical operation, they are also one of the most widely used belt series in the industry. The premium A-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 a cotton with a polyester blend for a high durability cover. A 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.
