Abstract
A seismic isolation bearing for structures consisting a steel ball sandwiched between two horizontal, steel load plates. The load plates have a shallow, concave, conical recess of vertical, collinear axis. The cone axis passes through the ball centerline at rest. The load plates are bolted the structure under and above. Gravity restores the bearing's displacement in the lack of external forces. Lateral bearing forces are independent of displacements.
