The invention discloses a long-stroke roller-free side bearing of a railway freight car and a bogie. The side bearing comprises a wearing plate, a side bearing seat, a rubber elastomer, an outer sleeve and a cover plate; the wearing plate is mounted on the upper surface of the cover plate; the side bearing seat comprises a side bearing mounting plate and a side bearing column, a mounting hole is formed in the side bearing mounting plate, the rubber elastomer is connected between the outer sleeve and the side bearing column, the outer sleeve is supported on the lower side of the cover plate, acover plate through hole is formed in the cover plate, a wearing plate through hole is formed in the wearing plate, and the upper end of the side bearing column is slidably connected with the cover plate through hole and the wearing plate through hole. The side bearing seat has the function of a roller, and is simple in structure, light in weight, small in size, convenient to assemble and disassemble and low in maintenance and replacement cost; the side bearing cover plate and the rubber elastomer outer sleeve are connected in an interference fit mode and freely move in the vertical directionin a full-stroke mode. A gap is reserved between the metal cover plate and the side bearing seat, and enough large longitudinal and transverse rigidity can be provided.
