Carbon Bearings

GRAPHITAR carbon bearings can be manufactured with as simple or complex design as suites the application. Plain sleeve bearings may be designed with or without lubrication grooves with axial or spiral configurations being common. Bearing tolerances are also a significant design consideration as regard to the impact into the manufacturing process.

GRAPHITAR’s porosity permits “self lubricated” bearing applications. This factor also permits the use of GRAPHITAR as an air bearing material where the ability to control the porosity is essential in high precision applications. Keeper plates and other mechanical accessories must be designed to provide evenly distributed support. Metal backed GRAPHITAR bearings are recommended for applications involving thermal or mechanical shock. GRAPHITAR is extremely resistant to rapid changes in temperature and, when combined with metal backing, tends to maintain a constant clearance as operating temperatures vary.
