The invention discloses a rolling wheel of an elevator landing door system. A metal shaft sleeve is arranged in a through hole, a second arc-shaped annular groove corresponding to a first arc-shaped annular groove is formed in the outer surface of the metal shaft sleeve, and balls are annularly distributed in a chamber formed by the first arc-shaped annular groove and the second arc-shaped annular groove together. The longitudinal part of a metal rolling wheel framework is sleeved with a Teflon outer ring, and one side face of the Teflon outer ring is in blocking connection with the transverse part of the metal rolling wheel framework. The longitudinal part of the metal rolling wheel framework is further sleeved with a metal backup shoe, and the metal backup shoe is located on the other side of the Teflon outer ring and is connected to the end face of the longitudinal part in a fastened manner. The technical aim of reducing the production cost of the rolling wheel of the elevator landing door system is achieved, and the beneficial effects that production cost is relatively low, the limitation of the specification and dimension of the product is small, and meanwhile the service life is long are achieved.
