Claim Text:
1. An apparatus for mapping liner wear of a bearing around a circumference of the bearing, the bearing having a ball, a liner, and an outer ring, the apparatus comprising: a rotary indexer that can hold the bearing, the ball disposed within the outer ring, the outer ring having an inner circumference, the bearing liner attached to the inner circumference of the outer ring; a shaft, the shaft being able to be inserted through a bore of the ball, the shaft is fixed at both ends such that the shaft is unable to rotate; a force applying mechanism communicating with the shaft such that the force applying mechanism applies constant upward radial force on the shaft which applies upward force on the ball such that the force applied by the shaft causes the ball to press against the bearing liner; a rotating mechanism that can rotate the rotary indexer, the rotary indexer communicating with the outer ring such that the rotary indexer can rotate the outer ring; a digital displacement indicator for determining displacement of the ball from a vertical motion of the shaft; and, a recorder for recording the displacement of the ball at various rotational positions of the outer ring and analyzing the displacement to determine liner wear at rotational positions of the outer ring.
