Our products : Carbon Graphite Bearings & Bushings

Carbon Graphite Bearings & Bushings

Helwig Carbon Products has been manufacturing carbon graphite bushings and bearings for over 40 years.  Self lubricating carbon graphite bushings are ideal for application 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).
