[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] As shown in Figures 1, 2 and 3, the deep groove ball bearing assembly with good lubrication effect includes a bearing body 1 and a bearing seat body 10 for mounting the bearing body 1. The bearing body 1 is composed of an inner ring, an outer ring, a retainer, balls and a sealing ring. The inner ring, the outer ring and the sealing ring cooperate to form a mounting cavity for mounting the balls and the retainer in the bearing body 1. Two limiting rings connected to the bearing seat body 10 and used to limit the position of the bearing body 1 after assembly are provided in the bearing seat body 10. One of the limiting rings can be integrated with the bearing seat body 10. On one end surface of the bearing seat body 10, A mounting groove 2 is provided along its length and extends to the bearing body 1 for the installation of lubricating oil. A through hole 3 is provided on the outer peripheral wall of the outer ring at the installation cavity to connect the mounting groove 2 and the installation cavity. The bearing seat body 10 is provided with a sealing cover 4 connected to it at the opening of the mounting groove 2 and used to enhance the sealing performance. A filling unit is provided in the bearing seat body 10 that is connected to it and cooperates with the mounting groove 2 and fills the lubricating oil in the mounting groove 2 into the installation cavity. The filling unit consists of two filling rods 5. The end face of the bearing seat body 10 at the mounting groove 2 is provided with a Two filling grooves 6 for installing corresponding filling rods 5 and slidingly cooperating with corresponding filling rods 5, the filling grooves 6 are arranged parallel to the installation groove 2, and the two filling grooves 6 are respectively located on both sides of the installation groove 2. The outer peripheral walls of the two filling rods 5 at the inner ends are embedded with a number of sealing rings to enhance the sealing performance.
