[0002] Bearings are an important component in modern mechanical equipment. Its main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearing rings refer to annular parts for bearings with one or more raceways. Their main function is to directly contact the surface of shaft workpieces or the inner wall of the installation groove, bear the load and limit the rolling elements of the bearings.

[0029] Four second sliders 8 are symmetrically fixed on both sides of the sealing ring plate 7, and the second sliders 8 are slidably connected to the slide groove 5. The two sealing ring plates 7 are connected with oil pipes 16. When the bearing is in use, a plug is provided at the oil pipe 16 to play a sealing role. The inner diameter of the sealing ring plate 7 is larger than the outer diameter of the inner ring 2. A wear-resistant sealing ring 11 is provided on the sealing ring plate 7. Two arc-shaped positioning rods 12 are symmetrically provided on one side of the sealing ring plate 7. A clamping plate 13 is fixed at one end of the arc-shaped positioning rod 12.
