Claim Text:
1. A K-type cage bearing comprising a cage which has an opening along a circumferential direction thereof, wherein the cage comprises: two coaxial lateral rings; and a plurality of transverse bars set between the two lateral rings and spaced along the circumferential direction, wherein two ends of each transverse bar are respectively connected with the two lateral rings, and among the plurality of transverse bars, those two of transverse bars located adjacent to the opening of the cage are respectively defined as a first transverse bar and a second transverse bar; wherein both the first transverse bar and the second transverse bar are configured with at least one connection element, all the connection elements extend from the first or second transverse bar into the opening of the cage, and the at least one connection element on the first transverse bar faces the at least one connection element on the second transverse bar along the circumferential direction in a one to one manner; wherein between two of the connection elements which face to each other along the circumferential direction, one of the connection elements is configured with an inserting block, while the other of the connection elements is configured with a groove, and the inserting block is adapted to be inserted into the groove; and wherein the groove comprises a first side surface and a second side surface, the first side surface faces, along the circumferential direction of the cage, toward a transverse bar of the first transverse bar and the second transverse bar to which the connection element configured with the groove is attached and is adapted to limit the inserting block from moving along the circumferential direction, and the second side surface faces to one of the lateral rings along an axial direction of the cage and is adapted to limit the inserting block from moving along the axial direction.
