The invention discloses an elevator roller of an elevator landing door system. A section of a metal roller frame is T-shaped; a longitudinal part is in a hollow structure; a limit check ring extending in the radial direction of a through hole is arranged on the through hole orifice edge, on the same side with a transverse part, of the longitudinal part; a metal shaft sleeve is arranged in the through hole of the longitudinal part; the end part of one side of the metal shaft sleeve is in blocking connection with the limit check ring; an annular gap is formed between the outer circumferential surface of the metal shaft sleeve and the inner hole wall of the through hole; multiple pin rollers are distributed in the circumferential direction of the metal shaft sleeve in the annular gap, and each pin roller is parallel to a central axis of the metal shaft sleeve; a non-metal outer ring is connected to the longitudinal part of the metal roller frame in a sleeving manner; a metal backup shoe is further connected onto the longitudinal part of the metal roller frame in a sleeving manner; the metal backup shoe, the metal shaft sleeve and the metal roller frame are riveted through end port of the longitudinal part of the metal roller frame. According to the roller of the elevator landing door system, the technical problem about reduction of the production cost of the elevator roller of the elevator landing door system is solved, and the production cost is low.
