The utility model relates to the technical field related to automobile part manufacturing, in particular to a high-stability roller needle bearing which comprises an outer ring, a middle ring and an inner ring, the outer ring is fixedly installed on the outermost side, the middle ring is movably installed in the outer ring, the inner ring is movably installed in the middle ring, a sound absorption structure is fixedly arranged in the outer ring, and the sound absorption structure is fixedly arranged in the middle ring. According to the utility model, the plurality of sound absorption ports are fixedly formed in the outer ring of the bearing, and the sound absorption plate is additionally arranged in the bearing, so that when a common bearing operates, certain friction noise can be generated due to rotating operation, but the noise is greatly reduced in the operation of the bearing, and the noise is collected into the sound absorption plate through the sound absorption ports, so that the noise is effectively r
