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.
Kaibintech cogged v-belt’s applications

J Section Multi-Rib V-Belt is a power transmission V-belt for drives with a small diameter sheave. It is made of CR(Chloroprene rubber) or EPDM (ethylene propylene diene monomer) rubber for resistance to weathering, oils, water, and some solvents. It has a truncated profile for increased flexibility and reduced heat buildup on high-speed drives with small diameter sheaves. It has fiber-reinforced ribs for resistance to wear and is smooth running for minimal vibration at high speeds. This V-belt is with oil and heat resistance standards and static conductivity requirements and is suitable for use with applications such as appliances, outdoor power equipment, roller conveyors, machine tools, medical equipment, and exercise equipment.
