Abstract

A bearing comprising a static component, a liner, a wear indicating sensor and a movable conductive component that will wear the liner, a) where the wear indicating sensor is first affixed to the static component, and said sensor is comprised of a first insulating layer in contact with the static component and a second conductive layer, configured such that the metallic layer and the static component are not in electrical contact, and b) where the liner is positioned between sensor and the moving component, where the liner comprises an insulating layer and a conductive layer, configured such that the insulating layer faces the moving metallic component, and the conductive layer faces the sensor, such that the conductive layer is in electrical contact with the conductive layer of the sensor.
