'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. Basic Information. Configure. Clear All. 185 Part Numbers. View Part Numbers.

Each type features the basic trapezoidal shape but has different dimensions. Standard v-belt. Standard v-belts are common in power transmission applications. These v-belts come in various types, as shown in Table 1. Each type varies from one another with respect to its Classical. This standard was developed in the 1930s. It now comes in six sizes (A, B, C, D, E and Z). Narrow. 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). VuIZY.
