CANTILEVERED TRACK ROLLER IN GROUND-ENGAGING TRACK SYSTEM AND ROLLER SHELL FOR SAME

摘要

A ground-engaging track system includes a track roller having a roller shell with an outer tread surface, and a roller shaft supporting the roller shell for rotation and cantilevering the track roller to a track roller frame. The track roller is positionable in the track system to contact only one of a first track rail or a second rail in a ground-engaging track.
