The invention discloses an elevator wheel. The section of a metal rolling wheel framework is in a T shape and is of a hollow structure, and a limiting check ring extending in the longitudinal direction of a through hole is arranged on the opening edge of the through hole, in the same side with a transverse part, of a longitudinal part. A first arc-shaped annular groove is arranged on the inner hole wall of the through hole, and a metal shaft sleeve is arranged in the through hole; and a second arc-shaped annular groove corresponding to the 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. A non-metal outer ring is connected to the longitudinal part of the metal rolling wheel framework in a sleeving manner, an R groove is formed in the surface of the peripheral ring of the non-metal outer ring, and arc-shaped grooves are annularly distributed in the R groove along the circumferential track of the non-metal outer ring. The longitudinal part of the metal rolling wheel framework is sleeved with a metal backup shoe, and a metal pressing plate, the metal shaft sleeve and the metal rolling wheel framework are riveted. The technical aim of reducing the production cost of the elevator wheel is achieved, and the production cost is relatively low.
