The utility model relates to a new type of excavator supporting wheel, which comprises a rotating shaft, a wheel body on the rotating shaft and a side cover on both sides of the wheel body. The features are as follows: a side cover step is arranged on the side cover, and a wheel body step with a labyrinth seal formed on the side cover step is arranged on the wheel body, and a side cover cavity is arranged on the inner side of the side cover step, and the upper position of the wheel body is arranged on the side cover step. The inner side of the wheel step is provided with a wheel body cavity. The side cover cavity is combined with the wheel body cavity to form a sealing cavity. The side cover cavity is provided with a side cover O-ring, and the wheel body O-ring is arranged in the wheel body cavity. The side cover floating oil seal with the side cover O-ring is arranged in the sealing cavity, and the wheel body floating oil seal with the side cover O-ring is arranged in the sealing cavity. The side cover floating oil seal and the wheel body floating oil seal are mutually opposed and symmetrically arranged along the relay position. The utility model solves the technical problem that the sealing effect of the existing supporting wheels is not good.
