Abstract
A compound rim assembly for a rotatable idler in an undercarriage system of a track-type machine includes a one-piece annular base configured for mounting the compound annular rim assembly upon an outer peripheral surface of an idler hub. The one-piece annular base is formed of a relatively lower hardness metallic material, and the compound rim assembly further includes a first annular track contacting rim a second annular track contacting rim positioned upon the one-piece base and being formed of a relatively higher hardness metallic material. The compound rim assembly further includes a track guiding ring trapped axially between the first and second annular track contacting rims and abutting the outer cylindrical surface of the one-piece annular base, the track guiding ring being formed of a non-metallic material and projecting radially outward of the first and second annular track contacting rims.
