A track roller made of light-weight metal, for track-laying running gear is composed of two track roller components which enclose in their central plane a circumferential guide groove for the track-guiding teeth of the track. The edge areas of the guide groove which come into engagement with the track-guiding teeth are equipped with in each case one washer made of wear-resistant material. In order to provide a simple attachment of these washers, each washer is designed in the manner of a cup spring, devices being provided with which each washer can be pressed on with the elastically widened inner annular opening onto a support surface of the respective track roller component.
