Abstract: A roller structure and a manufacturing method thereof are introduced. The roller structure includes a cylindrical roller rotatable about an elongated axial portion disposed coaxially in a through-hole of the cylindrical roller, a bush with an end fixed to an end of the elongated axial portion, the bush having a first stop portion positioned proximate to one axial end of the cylindrical roller and another end having an engaging portion coupled to a load, and a second stop portion disposed at an opposite end of the elongated axial portion and positioned proximate to the other side of the roller such that the roller rotates between the first stop portion and the second stop portion. Hence, the roller structure and the manufacturing method thereof provide a modularized roller structure for carrying a load, effectuate modularized assembly and production, enhance assembly efficiency, attain structural streamlining, and cut costs.
