The Dodge Baldor 3-3V3.15-SH Sheave is a three-groove V-belt pulley for 3V belts, featuring a 3.15 in outside diameter and a 3.1 in pitch diameter. It uses a QD-bushed SH-series bore in cast iron, with an overall width of 1.50 in and a through-bore length of 1.3125 in, and it accepts shaft bores from 7/16 to 1-11/16 in; keyways are available in multiple standard sizes. Weighing 2.25 lb, the pulley isolates shock loads and vibration and supports drive ratios of 6:1 or higher with typical efficiency around 95% and no lubrication required. The SH bushing system provides reliable mounting on standard shafts, making this pulley a compact, durable choice for 3V belt drives in industrial equipment.
