Abstract:

A roller assembly for an undercarriage of a work machine has a roller rim having (i) central passage, and (ii) an inwardly extending annular flange defined therein. The inwardly extending annular flange extends into the central passage so as to define a flange opening having a first diameter. The roller assembly also has a roller shaft having a first end portion which is positioned outside of the central passage of the roller rim and a second end portion which is positioned within the central passage of the roller rim. The second end portion of the roller shaft has an outwardly extending annular flange secured thereto. The outwardly extending annular flange of the roller shaft has a second diameter. The second diameter is greater than the first diameter. An undercarriage for a work machine is also disclosed.
