Self lubricating carbon graphite bushings & bushings are ideal for applications where normal lubricants can not be used. Even high temperature applications are not a problem for carbon graphite. We have a wide selection of grades and sizes in stock and have the ability to manufacture custom parts quickly. With our CNC equipment we manufacture a wide variety of shapes and routinely hold tolerances of 0.0005” (0.013 mm).
