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. Locate the corresponding belt type and size on the chart: Once the current belt type and size have been identified, locate the corresponding size and type on the V-belt conversion chart. The chart will provide information on the different types of V-belts and their corresponding sizes. Each of these belts has a 1/2-inch top width and 50-inch circumference. However, notice the differences in cord materials, body compounds, cover configurations, temperature ranges and application requirements. Despite their outward similarities, each of these belts is designed for a distinct purpose. 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 What are the different v-belt sizes? There are many different v-belt sizes. Some common sizes are standard (Z, A, B, C, D, E), narrow (3V, 5V, 8V), wedge (SPZ, SPA, SPB, SPC), hexagonal (AA, BB, CC), and fractional horsepower (2L, 3L, 4L, 5L).

Size Isn't Everything. Take a look at the accompanying chart (Figure 1). 'A', 'B', 'C', 'D' and 'E'. The categorization of this is based on the cross sectional size of the belt and the amount of power to be transmitted by the belt. The dimensions of various sections of the V-belt are shown below. The included angle of the V-Belts is 40 Degrees. l4hA.
