Zusammenfassung:	The utility model relates to the technical field of bearings, in particular to a straightener bearing which comprises an outer ring, a ball groove and sealing ring grooves which are distributed in parallel are formed in the inner wall of the outer ring, and the sealing ring grooves are located on the two sides of the ball groove. Two groups of ball grooves and two groups of sealing ring grooves corresponding to the ball grooves and the sealing ring grooves in the outer ring are formed in the outer wall of the inner ring; the retainer is located between the outer ring and the inner ring and comprises two sections of annular frame bodies, ball containing penetrating holes are evenly distributed in the frame bodies, the ball containing penetrating holes are round penetrating holes with openings in the side faces, and arc-shaped grooves matched with the openings of the round penetrating holes are formed between the round penetrating holes. The balls on the retainer are filled in the circular through holes and the
