The present disclosure discloses a bearing positioning structure without radial interference fit, which is used for a step of an escalator, including: a bearing seat, a rolling bearing through which a step roller is installed on the bearing seat; wherein the bearing positioning structure also includes a bolt, a washer and a nut, the bearing seat has a central through hole coaxial with its circumferential surface, the bolt successively passes through the washer, a bearing inner ring of the rolling bearing, the central through hole and the nut, and the inner ring of the rolling bearing is clamped between the washer and an axial limit step of the bearing seat by tightening the nut. It can overcome the problems of low manufacturing and assembly efficiency, reduced component life and increased production cost caused by radial interference fit of bearing.
