Fractional V-belts are designed for which type of applications?

Fractional V-belts are specifically designed for light-duty applications. These types of belts are typically used in smaller machinery and equipment, where the demands on belt performance are less intensive compared to heavy-duty or high-torque applications. They are common in household appliances, small fans, and light industrial equipment, where effective power transmission is necessary, but the load and torque do not exceed moderate levels.

The design of fractional V-belts allows them to operate efficiently in these environments, providing sufficient grip and flexibility to handle the lower horsepower requirements without excessive wear or slippage. Their geometric design also favors lower tension, which is suitable for lighter applications, making them ideal for everyday machinery that doesn't require the robust performance associated with heavier-duty belts.
