3LX Series Cogged FHP V-Belts – Enhanced Flexibility and Efficiency for Light-Duty Power Transmission
The Classical 3LX Series Cogged Fractional Horsepower (FHP) V-Belts are engineered to deliver superior performance in compact, lightweight drive systems where smooth operation and reliability are essential. Designed specifically for fractional horsepower applications, these belts incorporate a precision-molded cogged profile that dramatically improves flexibility, reduces heat buildup, and boosts overall energy efficiency—especially in high-speed or tight-center drives.
Optimized Design for Small Pulley Performance
With a top width of 3/8 inch (0.38") and a height of 7/32 inch (0.219"), 3LX belts maintain a slim, compact profile while offering strong, consistent power transmission. Their notched underside allows the belt to bend easily around smaller pulleys, reducing internal stress and extending service life. Manufactured from durable, heat-resistant rubber compounds and reinforced with high-strength polyester cords, 3LX belts provide excellent stability, reduced stretch, and dependable performance under varying load conditions.
