The present invention relates to a crawler belt track rocker set which comprises a pair of retaining structures and a rolling shaft. Each retaining structure includes a fixed holder and a radial bearing. The fixed holder is provided with a matching face and a mounting groove. The matching face and the mounting groove are arranged in such a manner that the mounting groove is formed by the indentation of the matching face. The radial bearing is firmly placed in the mounting groove and the radial bearing is provided with an outer ring, an inner ring and a plurality of rolling objects that are connected between the outer ring and the inner ring. The outer ring abuts against the fixed holder and the inner ring, with the help of the rolling objects, rotates relative to the outer ring. The rolling shaft is provided with a rod and a pair of connecting columns. The rod is provided with two end faces. The connecting columns protrude out of the shaft core of the rod from the two end faces respectively and are sleeved and connected firmly with the inner rings of the radial bearings of the pair of retaining structures to make the rolling shaft connected in a rolling manner between the pair of the retaining structures. The crawler belt track roller set provided in the invention has a fewer number of parts and is lighter in weight. For the fewer number of parts, chances that parts go wrong and the maintenance costs for the parts are reduced accordingly. It also features advantages of highly resisting bending, being easy to mount and achieving high precision.
