Abstract
A bearing material is formed from a body, a binder and a plurality of microcapsules uniformly dispersed in the binder and containing a lubricant. The microcapsules are adapted to be broken upon the exertion of a force and to release the lubricant. The lubricant may be a solid or a fluid. Lubricants having individual properties may be disposed in different microcapsules. For example, a lubricant operative to provide a lubrication at high temperatures may be disposed in some of the microcapsules and a lubricant operative to provide a lubrication at low temperatures may be disposed in other microcapsules. The body may be a fabric or may be formed from randomly oriented fibers defining a fibrous mat having a porous relationship.
