Fractional Horsepower V-belts

Fractional Horsepower V-belts

The 4L and 5L sections were dimensionally similar to A and B classical belts and can operate interchangeably on A and B sheaves. However, 4L and 5L belts have a lower power rating than classical A and B section belts. The 4L and 5L were originally termed FA (fractional A) and FB (fractional B), and 3L was formerly called FO.
