Glass fibers-glass beads-carbon fibers-aramid fibers-mineral fillers are available with varying contents in different combinations. And also filled materials containing PTFE and molybdenum disulphide are available for bearing materials with appropriately low friction and improved wear. Heat stabilizers-hydrolysis stabilizers-lubricants-UV stabilizers, electrical conductive etc. are being used in non-reinforced and reinforced grades to increase specific material properties.
