Abstract
The invention especially relates to a track roller bearing, which belongs to the technical field of sports equipment. The track roller bearing overcomes the problem of unreasonable design of traditional track roller bearings and comprises an outer bearing ring, an inner bearing ring and a plurality of balls. The outer side of the outer bearing ring is circumferentially provided with an inwardly-recessed annular groove; the bottom of the annular groove is provided with circumferentially arranged and inwardly-recessed annular recessed groove; an annular antiskid loop prepared from a flexible material is arranged in the annular recessed groove; the circumferential outer side of the annular antiskid loop exceeds the annular recessed groove and is provided with a plurality of first flexible humps and second flexible humps; and the first flexible humps and second flexible humps are different in length and are arranged in an alternately staggered way. The track roller bearing has the following advantages: good stability and high strength are obtained; skidding between the track roller bearing and a raceway hardly occurs in use of the track roller bearing, and the track roller bearing steadily rotates; and since the annular antiskid loop is prepared from the flexible material, generation of noise in use of the track roller bearing is prevented, and the annular antiskid loop is firmly positioned.
