Abstract
A bearing assembly includes a bearing base and a plurality of tiltable shoes. A ceramic plate is bonded to each shoe and a face surface of each ceramic plate provides a bearing face. Tilting movement of the shoes relative to the bearing base provides a fluid lubrication film wedge between the bearing faces and the running surface of a moving load. The ceramic plates are separately produced and are bonded to the surface of the shoes, which are formed of relatively soft material, by adhesive, soldering, welding or sintering. The running surface of the load may be formed of a ceramic layer. The ceramic plates are formed of silicon carbide which is fiber reinforced.
