[0026] As shown in Figure 1 to Figure 6 shown:

[0027] The present utility model provides a deep groove ball bearing for a stable damping shock absorber, including a bearing body 1; the bearing body 1 is provided with an outer ring 2 of the bearing in the up and down direction, which is convenient for carrying various components. The outer circumference of the outer ring 2 of the bearing is provided with stop ring grooves up and down, which is convenient for the stop arc ring 3 to be clamped. The inner circumference of the outer ring 2 of the bearing is provided with an annular raceway in the middle, which is convenient for the spherical rolling element 9 to roll. The inner circumference of the outer ring 2 of the bearing is provided with annular clamping grooves up and down, which is convenient for the bearing end cover 5 to be snapped in and installed. The stop arc ring 3 is clamped in the stop ring groove of the outer ring 2 of the bearing, which is convenient for limiting one end of the outer ring 2 of the bearing. A clamping port is provided on the left side of the stop arc ring 3, which is convenient for disassembly and assembly. An inner ring 4 of the bearing is provided inside the outer ring 2 of the bearing in the up and down direction, which is convenient for installation on the rotating shaft. The outer circumference of the inner ring 4 of the bearing is provided with an annular raceway in the middle, which is convenient for the spherical rolling element 9 to roll. The outer circumference of the inner ring 4 of the bearing is provided with annular clamping grooves up and down, which is convenient for the bearing end cover 5 to be installed. Bearing end covers 5 are clamped and installed at both upper and lower ends between the outer ring 2 of the bearing and the inner ring 4 of the bearing, which is convenient for sealing and dust prevention. Elastic cards are annularly arranged on the inner circumference of the bearing end cover 5 and on the outer circumference of the outer circumference, which is convenient for snapping in and disassembly.

[0028] Among them, a perforated half-cage 6 is arranged at the upper part inside between the bearing outer ring 2 and the bearing inner ring 4 to facilitate the interval positioning of the spherical rolling elements 9. Through holes penetrating up and down are annularly arrayed on the perforated half-cage 6 to facilitate the insertion of the pillar half-cage 7.

[0029] The specific usage mode and function of this embodiment:

[0030] In this utility model, when the bearing body 1 is installed, the stop arc ring 3 at one end of the bearing outer ring 2 is removed, and the end of the bearing outer ring 2 without the stop arc ring 3 is placed into the installation hole, and then the axial limit during installation is carried out through the stop arc ring 3 at the other end of the bearing outer ring 2; when the perforated half-cage 6 and the pillar half-cage 7 are disassembled, first remove the bearing end cover 5, and then rotate the assembly locking cylinder 8 through a tool to be thread-engaged with the pillar half-cage 7, so that the assembly locking cylinder 8 rises through thread engagement and disengages from the threaded posts of the pillar half-cage 7, move the perforated half-cage 6 upward to take it out, and move the pillar half-cage 7 downward to take it out, thus completing the disassembly of the perforated half-cage 6 and the pillar half-cage 7. Embodiment Two:

[0031] The difference from Embodiment One is that the inner circumferential surface of the stop arc ring 3 can also be set as a frosted surface, thereby increasing the friction between the inner circumferential surface of the stop arc ring 3 and the bearing outer ring 2 to prevent the stop arc ring 3 from rotating. Embodiment Three:

[0032] The difference from Embodiment One is that the bottom end face of the assembly locking cylinder 8 can also be set as a frosted surface, thereby increasing the friction between the bottom end face of the assembly locking cylinder 8 and the perforated half-cage 6 to prevent the assembly locking cylinder 8 from rotating and loosening.
