An idler (20) for an undercarriage system (12) in a track-type machine (10) includes an idler rim (30) having an outer rim surface (32) extending circumferentially around an idler axis of rotation (34) and forming a centrally located guide flange (36). The outer rim surface (32) further forms a first ring channel (40) and a second ring channel (42) upon a first axial side and a second axial side of the centrally located guide flange (36), respectively. A first sacrificial wear ring (44) is seated in the first ring channel (40) and a second sacrificial wear ring (46) is seated in the second ring channel (42).

    La présente invention concerne une roue de support (20) pour un système de train de roulement (12) dans une machine de type chenille (10) qui comprend un bord (30) de roue de support présentant une surface de bord externe (32) s'étendant de manière circonférentielle autour d'un axe de rotation (34) de roue de support et formant une bride de guidage située au centre (36). La surface de bord externe (32) forme en outre un premier canal annulaire (40) et un second canal annulaire (42) sur respectivement un premier côté axial et un second côté axial de la bride de guidage située au centre (36). Une première bague d'usure sacrificielle (44) est logée dans le premier canal annulaire (40) et une seconde bague d'usure sacrificielle (46) est logée dans le second canal annulaire (42).
