The invention discloses a step chain roller for a double-injection-molded escalator, relates to the technical field of step chain roller structures, and aims to solve the problems that the adhesiveness of an existing step chain roller for the escalator is poor, and when the existing step chain roller is subjected to external force, a gap is possibly formed between a polyurethane tire bead and a hub; and after a long time, falling and separation may occur. Grooves are formed in the two ends of the hub correspondingly, reinforcing ribs are arranged in the grooves, a bonding end is arranged at one end of the outer wall of the hub, a special-shaped groove is formed in the bonding end, limiting mounting grooves are formed in the two ends of the bonding end correspondingly, and friction stripes are arranged in the outer wall of the bonding end. A bonding end is arranged on one side of the tire body, a polyurethane tire bead is mounted on one side of the bonding end, a special-shaped connecting seat is arranged at one end of the polyurethane tire bead, limiting mounting ends are arranged on the two sides of the polyurethane tire bead, and a limiting clamping seat is arranged at one end of each limiting mounting end.
