A structure for standardizing at least one kind of part of a roller assembly for a construction vehicle so that the part can be used for a same size of construction vehicles having different structural specifications of a plurality of construction vehicle makers. The at least one kind of part includes at least one of a shell, a shaft, a floating seal, a bushing and a collar. Structural specifications including the configuration and dimension, the kind of steel or material, and the heat treatment specification or the mechanical property for the at least one kind of part are unified as much as possible over the same size of the construction vehicles of a plurality of construction vehicle makers.
