The undercarriage assembly includes a roller frame and a pair of wheels held in spaced apart relation by the roller frame. An endless track belt is entrained about the pair of wheels. A bogie arm is pivotally connected to the roller frame at a pivot axis. The bogie arm includes a roller arranged and configured for supporting the track belt between the wheels. The undercarriage assembly also includes an elastomeric bearing positioned about the pivot axis of the bogie arm for reducing shock loads applied to the bogie arm. The elastomeric bearing can be arranged and configured to bias the bogie arm toward the track belt via torsion.
