Pulley > American Sheaves Dimensions

This Sheave uses a bushing, is directly interchangeable with other manufacturers, and is manufactured in accordance with ARPM Standard for safe operation. With  sheaves you can use kinds of banded v-belts. What separates this sheave from the others is that it is made using a high strength cast iron, is phosphate coated, painted, and balanced at the factory. Using the high-strength cast iron grade that we do offers a higher tensile strength and is more wear resistant than the more commonly used grades. While the phosphate coated and then painted finish adds corrosion resistance to the sheave. Then, because this sheave is balanced at the factory it runs smoother which gives bearings and other components of the equipment a longer working life. Using a quick detachable style sheave is beneficial because it makes the completed part a two piece assembly which means if only one piece breaks you don't have to replace the entire assembly.
