The invention discloses an elevator roller wheel of an elevator landing door system. The cross section of a metal roller wheel framework is T-shaped, and is of a hollow structure; the orifice of a through hole in a longitudinal part on the same side of a horizontal part is provided with a limiting check ring which longitudinally extends toward the through hole; a metal axle sleeve is arranged in the through hole in the longitudinal part; the end part of one side of the metal axle sleeve is in baffle connection with the limiting check ring; an annular clearance is formed between the peripheric ring surface of the metal axle sleeve and the inner hole wall of the through hole; multiple pin rollers are arrayed in the annular clearance along the peripheric ring direction of the metal axle sleeve; a nonmetal outer ring is in sleeve connection with the longitudinal part of the metal roller wheel framework; a metal pressure cover is also in sleeve connection with the longitudinal part of the metal roller wheel framework; the metal pressure cover, the metal axle sleeve and the metal roller wheel framework are riveted through the end opening of the longitudinal part of the metal roller wheel framework; and through pinholes are formed in the riveting surface so that the annular clearance is communicated with the external environment. The technical problem about how to lower the production cost of the elevator roller wheel of the elevator landing door system is solved, and the production cost is relatively low.
