The connecting groove 9 is located on one side of the sealing element 8, and one side of the connecting groove 9 has a trapezoidal structure and engages with the bearing inner core 1 and the bearing ring 3. The limiting plate 10 is symmetrically fixed at the upper and lower ends of the sealing element 8, and the limiting plate 10 is respectively engaged with the inner side of the bearing inner core 1 and the bearing ring 3. The connecting balls 11 are disposed on the outer side of the limiting plate 10. The connecting groove 9 allows for sealing of one side of the bearing inner core 1 and the bearing ring 3. The ball assembly 7 is limited to prevent it from derailing, thus ensuring the service life of the bearing. Subsequently, the sealing element 8 can ensure the normal rotation of the bearing inner core 1 and the bearing ring 3 while sealing their connection, preventing dust and other contaminants from entering the connection between the bearing inner core 1 and the bearing ring 3, thereby ensuring the service life of the bearing. The limiting plate 10 and the connecting ball 11 can limit the sealing element 8, preventing it from shifting or shaking. The connecting ball 11 can ensure that the bearing inner core 1 and the bearing ring 3 can rotate normally.

[0029] An oil chamber 12 is located inside the bearing core 1 on one side. An oil supply port 13 is connected to the lower end of the oil chamber 12. A push-adjustment mechanism is provided on one side of the oil chamber 12 to guide and push the lubricating oil within it. The push-adjustment mechanism includes a push plate 14 and an adjusting screw 15. The push plate 14 is slidably engaged with the inner side of the oil chamber 12, and a sealing ring is provided on the outer side of the push plate 14 to contact the inner wall of the oil chamber 12.
