The invention discloses a compartment elevator roller wheel. The section of a metal roller wheel framework is T-shaped. The metal roller wheel framework is of a hollow structure. Limiting stop rings extending in the radial direction of through holes are arranged on the opening edges of the through holes in the same side with a transverse part, on a longitudinal part. A first arc annular groove is formed in the inner hole wall of each through hole, a metal shaft sleeve is arranged in each through hole, a second arc annular groove opposite to the corresponding first arc annular groove is formed in the outer surface of each metal shaft sleeve, and rolling balls are annularly distributed in a cavity formed by each first arc annular groove and the corresponding second arc annular groove. A non-metal outer ring is connected to the longitudinal part of the metal roller wheel framework in a sleeving mode. A metal gland is connected to the longitudinal part of the metal roller wheel framework in a sleeving mode, and a metal pressing plate, the metal shaft sleeves and the metal roller wheel framework are riveted. Arc-surface R grooves are annularly distributed in the outer peripheral surface of the non-metal outer ring, and three annular grooves are formed in the bottom arc surface of each arc-surface R groove. The technical purpose that the production cost of the compartment elevator roller wheel is reduced is achieved, and the production cost is low.
