There are three common V belt types: Classical v-belt classified by their dimensions from A to E; narrow V series organized by their dimensions 3V, 5V, and 8V; FHP light-duty v-belts classified by their sizes 2L, 3L, 4L, 5L. The letter X classifies their counterpart cogged belt. For example, the Classical V cog belt will be 3VX, 5VX, etc. 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. There are several industry standards for the types and sizes of v-belts. 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 Basic Information.

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. Link to this Webpage: Engineers Edge: 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). Simply measure from the 1" mark across the top of the belt. Common widths range from ½" to as wide as 1½" to indicate whether you need anything from an A belt all the way up to an E belt. Measuring the V-Belt Length. There are a few different ways you can measure the length of a V-belt. 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. 3Dbj.
