Abstract
Abstract A slide bearing having a backing pad forming a substantially planar face on which a mesh is affixed. A piece of sheet bearing material is impaled on the mesh by the application of pressure and heat for permitting the bearing to support higher loads at higher temperatures than obtainable by attaching the bearing material directly to the pad as by a suitable adhesive.
