There are three common V belt types: Classical V-belt (classified by their dimensions from A to E), Narrow V series (classified by their dimensions 3V, 5V, and 8V), and light duty Fractional Horsepower belt (classified by their dimensions 2L, 3L, 4L, 5L). Their counterpart cogged belt is classified by the letter X.
What does a Poly V belt look like?
The Poly-V® belt is a single, endless belt with longitudinal V-shaped ribs that mate consistently with the V-grooves in the sheaves. It combines the convenience of a thin, one-piece flat belt with the strong gripping traction of multiple V-belts to make the Poly-V belt far better than either for many applications.
Are all V belts the same?
The types of V-belts and their standard sizes: There are three common V belt types: Classical V-belt (classified by their dimensions from A to E), Narrow V series (classified by their dimensions 3V, 5V, and 8V), and light duty Fractional Horsepower belt (classified by their dimensions 2L, 3L, 4L, 5L).
How do you read V belt numbers?
Automotive belts start with either 4L (12.5mm wide) or 3L (9.5mm). The number following it is the outside length of the belt in tenths of inches. The inside length of the belt is typically 2" less for a 4L belt, and 1-1/2" less for a 3L belt. An example would be 4L460, which would be 46" long outside, 44" inside.

How are V belts measured?
How to measure the belt: You will notice that all V belts also sometimes referred to as wedge shaped belts are measured across the top think section and the depth of the belt. This means you would measure the widest part of the belt (thick section) and then from the widest part to the narrowest part of the belt.
