A wear monitoring system is disclosed for use with a track type machine. The wear monitoring system may have at least a first radius sensor configured to generate a first signal indicative of a change in radius of at least one idler wheel, and a displacement sensor configured to generate a second signal indicative of a change in displacement of a track tensioning actuator. The wear monitoring system may also have a controller in communication with the first radius sensor and the displacement sensor. The controller may be configured to determine wear of a track link guided by the at least one idler wheel and tensioned by the track tensioning actuator based on the first and second signals.
