V-Ribbed V-Belts are ideal for high speed, and/or high drive ratio applications. They offer smooth, vibration-free performance in a single, compact drive belt. The belts are made of heat and abrasion resistant materials for long belt life. The ribs are truncated for maximum flexibility, reduced heat buildup and longer belt life. The belts meet or greatly exceed all requirements of USA belt standard RMA IP-26 for V-Ribbed belts.
