[0005] In the above-mentioned dust-proof sealed deep groove ball bearing, an annular groove for the sealing ring to extend into is provided on the inner ring of the bearing, and a sliding groove for the steel ball to slide is provided at the bottom of the annular groove.

[0006] In the above-mentioned dustproof sealed deep groove ball bearing, the positioning rod is provided with a groove for installing the positioning component, one end of the positioning member extends into the groove, and the other end of the positioning member extends out of the groove and abuts against the upper end of the seal to fix it.

[0007] In the above-mentioned dust-proof sealed deep groove ball bearing, the sealing member is provided with an opening for the positioning rod to pass through, and the positioning assembly is arranged at a height of the positioning rod that is the same as the height of the sealing member.

[0008] Compared with the prior art, the dustproof sealed deep groove ball bearing fixes the seal on the outer ring of the bearing by a positioning rod arranged on the outer ring of the bearing, and fixes the seal by a positioning assembly to facilitate the staff to disassemble and replace the seal.

[0013] 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.

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, the dust-proof sealed deep groove ball bearing comprises a bearing outer ring 1 and a bearing inner ring 2, a ball 3 is arranged between the bearing outer ring 1 and the bearing inner ring 2, a seal 4 is respectively arranged on the bearing inner ring 2 and the bearing outer ring 1 and at the upper end and the lower end of both, the bearing outer ring 1 and the bearing outer ring 1 are provided with a mounting groove 5 for installing the seal 4, a positioning rod 6 for positioning the seal 4 is fixedly arranged on the bearing outer ring 1, and a positioning rod 6 for positioning the seal 4 is arranged on the positioning rod 6 The positioning assembly 7 is composed of a positioning member 8 and a connecting spring 9. The positioning member 8 can be extended and retracted on the positioning rod 6 to fix the seal 4 on the bearing outer ring 1. The other end of the seal 4 is against the bearing inner ring 2. The lower end of the seal 4 is integrally provided with a sealing ring 10. The sealing ring 10 increases the sealing inside the ball 3 to prevent external factors from affecting the inside of the bearing and improve the service life of the utility model. A steel ball 11 is provided between the sealing ring 10 and the bearing inner ring 2.

[0015] To be more specific, the inner ring 2 of the bearing is provided with an annular groove for the sealing ring 10 to extend into, and the bottom of the annular groove is provided with a sliding groove for the steel ball 11 to slide.
