Sealing device of a bearing and bearing

A bearing, comprising:

• a first ring and a second ring that are nested with each other and are rotatable relative to each other, and
• a sealing device comprising:
• a framework;
• a sealing component and a plurality of elastic members, the framework and the sealing component are both annular and connected to each other;
• the framework is configured to be fixed to a first ring of the bearing;
• and
• the sealing component is configured to abut against a second ring of the bearing, the plurality of elastic members are distributed at intervals in a circumferential direction of the sealing component, and the elastic members apply an elastic force to the sealing component such that the sealing component is pressed against the second ring;
• wherein a plurality of through holes are formed in each of the elastic members, and the sealing component partially passes through the plurality of through holes.

A sealing device of a bearing, the sealing device comprising:
