[0006] Further, an adaptor inner ring is arranged inside the bearing outer ring, and rollers are arranged between the adaptor inner ring and the bearing outer ring. The adaptor inner ring is rotationally connected to the bearing outer ring through the rollers.

[0007] Further, locking seal rings are arranged at both ends of the adaptor inner ring. The locking seal rings are connected to the adaptor inner ring by screws. The locking seal rings can cooperate with the locking structure to complete the clamping and locking of the adaptor inner ring, so that it can quickly stop rotating without being affected by inertia.

[0008] Further, rubber ring teeth are arranged on the surface of the locking seal ring. The rubber ring teeth and the locking seal ring are arranged as an integral structure. The rubber ring teeth can increase the frictional resistance between the locking seal ring and the locking structure.

[0009] Furthermore, the vacuum pores extend above the locking seal ring, and the oil injection holes penetrate through the outer ring of the bearing and extend to the surface of the roller.

[0010] Furthermore, a limiting ring is arranged inside the vacuum pores, and a valve core is arranged below the limiting ring. Among them, the valve core is telescopically connected to the vacuum pores, and the limiting ring can prevent the valve core from being taken away from the vacuum pores during the air extraction process.
