    Abstract: A support roller for vehicle tracks, includes a tubular body rotatable on a supporting shaft integral with a chassis; the tubular body has an external surface for accommodating a portion of an internal face of a respective chain. The supporting shaft comprises at least three consecutive cylindrical segments having constant external diameters and increasing progressively from one segment to the next. The tubular body comprises an internal cavity provided with a first portion whose dimensions are complementary to the segment of said shaft that has the largest diameter and an intermediate portion, which in the assembly configuration faces and is proximate to a segment of the shaft having an intermediate diameter; the intermediate portion has a different diameter than the first portion. An annular interspace that accommodates rolling elements is formed between the segment having an intermediate diameter of the supporting shaft and the intermediate portion of the tubular body.
