Abstract
A bore gauge centralizer comprising a frame having a pair of parallel legs connected by a cross piece. One end of the frame is pivotally mounted to the gauge head so that the legs are generally parallel to the longitudinal axis of the gauge and the ends of the legs pivot in unison away from the head. A spring biases the leg ends away from the head. A roller is rotatably attached to the each leg end. The roller is a truncated solid oval so that a single contact point is made with the bore wall regardless of the position of the frame.
