How To Measure V-Belt Pulleys | Sizes & Dimensions

One of the ever-growing and most widely used product types in the power transmission and automotive industries is the V-belt pulley, also known as the “sheave.” A V-belt pulley is an attachment that transfers energy between axles with the help of a V-belt. However, to keep this critical pair of devices functioning correctly, one must secure the appropriate V-belt pulley replacement when an older one gets worn down. To do this, you need to know the size, dimensions, and type of your V-belt pulley so that the replacement will operate adequately. Learning to measure a V-belt pulley’s size and calculate its dimensions are simple tasks; however, correctly identifying a V-belt pulley type can be complex. V-belt pulleys come in various styles and options, including A-section, B-section, C-section, D-section, 3V-section, 5V-section, 8V-section, variable pitch, double groove, and metric pulleys. We stock over 8,000 different V-belt pulleys alone.
