McKissick (part of The Crosby Group) is a world leader when it comes to sheave manufacturing. They offer a multitude of sheave diameters for practically all sizes of wire rope, with custom sheaves available upon request. Below is an assortment of bronze bushed sheaves that are generally in stock. Why bronze bushed? Because bronze bushed sheaves are by far the most popular type of sheave we sell--they are good for slow line speed applications with moderate loads and moderate use.
