The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0021] The deep groove ball bearing comprises a deep groove ball bearing outer ring 1, a deep groove ball bearing inner ring 2, a steel ball 3 and a nylon retainer 4, wherein the steel ball 3 is mounted on the nylon retainer 4, and the nylon retainer 4 is arranged between the deep groove ball bearing outer ring 1 and the deep groove ball bearing inner ring 2. The deep groove ball bearing outer ring 1 comprises a sealing member 5 arranged between the deep groove ball bearing outer ring 1 and the deep groove ball bearing inner ring 2, and a supporting member 6 arranged on the sealing member 5. The deep groove ball bearing outer ring 1 is provided with a connecting hole 7 for inserting one end of the sealing member 5, and the deep groove ball bearing inner ring 2 is provided with a fixing hole 8, wherein the other end of the sealing member 5 can be deformed and inserted into the fixing hole 8, and one side surface of the sealing member 5 is in conflict with the side wall of the fixing hole 8 close to the steel ball 3 to seal the deep groove ball bearing.

[0022] Furthermore, as a preferred embodiment, installation spaces 9 are opened on both sides between the deep groove ball bearing outer ring 1 and the deep groove ball bearing inner ring 2, a seal 5 is installed in each installation space 9, and the fixing holes 8 and the connecting holes 7 are opened on the side walls of the installation space 9.

[0023] Further, as a preferred embodiment, one end of the sealing member 5 is bent upward to form a connecting portion 10, and the connecting portion 10 is inserted into the connecting hole 7. The other end of the sealing member 5 is bent upward to form a fixing portion 11, and the fixing portion 11 can be deformed and inserted into the fixing hole 8, and one side of the fixing portion 11 is in conflict with the side wall of the fixing hole 8 close to the steel ball 3. The sealing member 5 and the connecting portion 10 are provided with a supporting member 6. The sealing member 5 is made of plastic material. The supporting member 6 is made of metal material.

[0024] Specifically, in this embodiment, a connection space is provided on the outer ring 1 of the deep groove ball bearing and the inner ring 2 of the deep groove ball bearing, and a nylon retainer 4 is connected in the connection space, and a steel ball 3 is installed on the nylon retainer 4. An installation space 9 connected to the connection space is provided on both sides of the inner ring 2 of the deep groove ball bearing and the outer ring 1 of the deep groove ball bearing, and a seal 5 is provided between the installation holes, and the seal 5 is made of plastic material. The left side of the seal 5 is bent upward to form a connection part 10, and a support member 6 is provided on the side of the seal 5 close to the steel ball 3, and the support member 6 is made of metal material. The left side of the support member 6 is bent upward and provided on the side of the connection part 10 close to the steel ball 3, that is, the support member 6 is connected to the seal 5 and the connection part 10 of the seal 5, and a connection hole 7 is provided on the outer ring of the deep groove ball bearing, and the connection hole 7 is provided on one side wall of the installation space 9, and the connection part 10 is inserted into the connection hole 7. Because the seal 5 and the connecting part 10 are provided with a support member 6 made of metal (which will not deform), the left side of the seal 5 is connected and fixed to the outer ring 1 of the deep groove ball bearing, and the connecting part 10 and the connecting hole 7 are fitted together without any gap.

[0025] Specifically, in this embodiment, the right side of the seal 5 is bent upward to form a fixing portion 11, and a fixing hole 8 is provided on the inner ring 2 of the deep groove ball bearing, and the fixing hole 8 is provided on a side wall of the installation space 9. The fixing portion 11 is inserted into the fixing hole 8, and the fixing portion 11 can be deformed because it is made of plastic material, and inserted into the fixing hole 8 after deformation, and inserted into the fixing hole 8 after restoration of deformation to seal the outer ring 1 of the deep groove ball bearing and the inner ring 2 of the deep groove ball bearing. The side surface of the fixing portion 11 close to the steel ball 3 is in conflict with the side wall of the fixing hole 8 close to the steel ball 3, thereby sealing the outer ring 1 of the deep groove ball bearing and the inner ring 2 of the deep groove ball bearing.
