Full roller linear-contact self-aligning bearing without holder

The invention discloses a full roller linear-contact self-aligning bearing without a holder. The full roller linear-contact self-aligning bearing comprises an outer ring, an inner ring and one or morerows of rolling bodies, wherein one or more ring-shaped roller paths are arranged between the outer edge of the inner ring and the inner wall of the outer ring; one row of rolling bodies is arrangedin each ring-shaped roller path; each row of rolling bodies comprises a plurality of rollers which tightly fit to each other, and the rollers can roll in the corresponding ring-shaped roller path, themiddle parts of the rollers are cylindrical, and the two ends of each roller are in the shapes of circular table bodies; and when two or more rows of rolling bodies are provided, the distance from the center point of each roller to the center point of the axis of each bearing is the same. The full roller linear-contact self-aligning bearing can reduce friction between the roller and the holder, and reduces manufacturing an
