Conventional V-Belt Sizes. V and Flat Belt Design and Engineering Data. V Belt sections given sizes are Inches/Millimeter. Cross Section Selection: Special circumstances (such as space limitations) may lead to a choice of belt cross section different from that indicated in the illustrations below.

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 (ranked by their sizes 3V, 5V, and 8V), and light-duty Fractional Horsepower belt (classified by their dimensions 2L, 3L, 4L, 5L).
V-belts are used in a variety of machinery, including industrial compressors, pumps, and conveyors, and selecting the correct V-belt is crucial for optimal machinery performance and safety. A V-belt cross reference chart contains information on the different types of V-belts and their corresponding sizes across different manufacturers.
This International Standard defines terms relating to V-belt drives, V-belts, hexagonal belts, joined V-belts and the corresponding V-grooved pulleys, V-ribbed belt drives, V-ribbed belts and V-ribbed pulleys, as well as the corresponding symbols.

Procedure 5: Selection of Belt Size Using the given center distance and the size of the large and small sheaves selected, calculate the belt length. For this purpose the following equation is used. C = Center Distance D = Outer Diameter of Large Sheave d = Outer Diameter of Small Sheave Belt Size = 2C + 1.57 (D+d) + (D-d)2 4C
In this article we'll review some V- belt basics to help you make better sense of which belt to use in a given ap- plication to make your belt drives last longer, run more eficiently, and save you downtime and money. Size Isn't Everything. Take a look at the accompanying chart (Figure 1).
