Power Transmission Fractional Horsepower L Series V-Belts
Precision, Reliability, and Smooth Power for Light-Duty Drives
Fractional Horsepower (FHP) L Series V-Belts are engineered to deliver consistent, efficient power transmission in light-duty applications where precision and quiet operation are essential. Designed for use with fractional horsepower motors and compact mechanical systems, these belts provide dependable performance across a wide range of commercial, residential, and light-industrial equipment.
Built for Compact Systems and High-Speed Operation
Classical L-Section Profile for Optimal Grip
L Series V-Belts feature a 3/8" (0.38") top width and a classical L-section V profile, providing excellent traction, reduced slippage, and smooth engagement in smaller pulley systems. Their compact size makes them ideal for installations where space is limited but performance cannot be compromised.
Durable Construction for Long Service Life
Manufactured from premium rubber compounds and reinforced with high-tensile polyester cords, these belts deliver the flexibility required for small-diameter pulleys while maintaining strength under load. They are oil and heat resistant, offer dependable operation in temperatures from -30°F to 140°F, and include antistatic properties that meet ISO and RMA safety standards.
Versatile Applications Across Light-Duty Equipment
L Series FHP belts are widely used in:
-
HVAC blowers and fans
-
Home and commercial appliances
-
Office machinery
-
Light-duty conveyors
-
Power tools and woodworking machines
-
Small agricultural implements
Their efficiency and durability make them a cost-effective choice for both replacement and OEM installations.
Understanding L Series Belt Length Terminology
Pitch Length (Lp)
The effective working length measured at the pitch line—located near the center of the belt’s cross-section—where it engages the pulley.
Outside Length (La or Lo)
The measurement taken around the outermost surface of the belt, representing the longest physical length.
3L Belt Pitch vs. Outside Length
For 3L-section belts, manufacturers generally use the guideline:
Pitch Length = Outside Length – 1.5 inches
This approximation helps ensure proper fit and performance when selecting replacement belts.
Whether you're designing a new light-duty drive or replacing worn components, Fractional Horsepower L Series V-Belts offer the smooth, quiet, and reliable power transmission your equipment depends on. Trust L Series belts to deliver long-lasting performance with minimal maintenance and maximum efficiency.
