ABSTRACT:
A method and apparatus are disclosed for non-invasively determining the wear of a liner separating a rotatable bearing from a generally spherical housing. The method includes digitizing a first radiographic image of the bearing and housing and processing elements making up the image to define and locate the centers of the bearing and housing within the image. The process is also undertaken for a second radiograph image of the bearing and housing taken earlier than the first radiograph. The movement of the center of the bearing relative to the center of the housing during the time period between the making the first radiographic image and the second radiographic image being related to the wear of the liner.
