3LX Series Classical Cogged V Belt

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 the perfect solution for compact, lightweight drive systems where space is limited, and performance is critical. Designed for smooth operation on smaller pulleys and light-duty equipment, 3LX belts feature a precision-engineered cogged profile that increases flexibility, reduces heat buildup, and improves energy efficiency.

With a top width of 3/8 inch (0.38") and a depth of 7/32 inch (0.219"), 3LX cogged belts maintain a compact form while delivering reliable grip and power transmission. The notched (cogged) underside allows for tighter bend radii and reduces internal stress, making them ideal for high-speed or short-center applications. These belts are constructed from high-performance rubber and reinforced with durable polyester cords for added strength and stability.
