3L Series Fractional Horsepower (FHP) V Belts

Power Transmission Fractional Horsepower L Series V-Belts – Precision Drive for Light-Duty Applications

When performance and precision matter in light-duty drives, Fractional Horsepower (FHP) L Series V-Belts deliver dependable, smooth power transmission. Engineered for fractional horsepower motors and compact mechanical systems, these belts are ideal for a wide range of light industrial and commercial applications.

L Series V-belts, part of the classical V-belt family, are specifically designed for low-torque, high-speed power transmission in systems requiring minimal space. With a 3/8-inch (0.38") top width and a V-shaped profile, they provide excellent grip, reduced slippage, and quiet operation. Constructed from high-quality rubber compounds and reinforced with polyester cords, these belts ensure long service life, high flexibility, and consistent performance in small pulley systems.

Often found in equipment such as HVAC systems, appliances, woodworking machines, and office machinery, L Series belts offer a cost-effective and efficient solution for fractional horsepower requirements.

Definitions:

• Pitch Length (Lp):
  The length measured at the pitch line — this is where the belt effectively rides on the pulleys (approximately at the center of the belt’s cross-section).

• Outside Length (La or Lo):
  The length measured around the outermost surface of the belt — the longest measurable length.

3L V-Belt Pitch vs. Outside Length:

For 3L belts, the difference between the pitch length and the outside length is typically:

Pitch Length = Outside Length – 1.5 inches

This is a general rule of thumb used by many belt manufacturers.

Whether you're replacing worn belts or designing a new light-duty drive, L Series Fractional Horsepower V-Belts are your go-to for quiet, efficient, and reliable performance. Trust these belts to keep your equipment running smoothly with minimal downtime.
