A track-supporting roller assembly, according to the disclosure, for supporting a crawler track of a crawler chassis includes a bearing unit and a track-supporting roller rotatably coupled to the bearing unit. The track-supporting roller includes at least one supporting body made of plastic. The supporting body serves as a damper and prevents a metal-on-metal contact between track chain links of the crawler track and the track-supporting roller. The track-supporting roller assembly according to the disclosure ensures a reduced noise development in the crawler chassis. At the same time, it is possible to also reduce the wear of the track-supporting rollers to a considerable extent.
