Fractional horsepower belts are typically used in which type of application?

Fractional horsepower belts are primarily designed for light duty applications. These belts are characterized by their ability to transmit small amounts of power, typically less than one horsepower. They are commonly found in equipment such as office machines, small pumps, fans, and similar applications where loads and speeds are relatively low.

Light duty applications benefit from fractional horsepower belts because they are cost-effective, easy to replace, and suitable for the lower operational stresses involved. The design and material of these belts allow them to operate efficiently in environments where the demand for power transmission is minimal.

In contrast, heavier duty applications usually involve higher power requirements and loads that necessitate more robust belt designs, which fractional horsepower belts are not intended to handle. Thus, it is clear why the designation of these belts is linked directly to light duty applications.
