More Information
Summary:A self-lubricating structure such as a bearing having a low coefficient of friction, a high bearing load capability, and a low abrasiveness is provided. The self-lubricating bearing has a PTFE-based sliding layer that is deposited on a metal backing layer. The sliding layer includes a PTFE-based matrix, self-lubricating fillers such as liquid crystalline polymer, and high temperature reinforcing fiber such as carbon fiber. A method for producing the self-lubricating bearing is also provided.
