The invention discloses a bearing sealing component and belongs to the technical field of mechanical accessories. The bearing sealing component comprises a sealing component main body arranged between a bearing outer ring and a bearing inner ring, wherein the outer end of the sealing component main body is arranged in the bearing outer ring in a sleeving manner; the inner end of the sealing component main body is provided with a clamping head; an annular oil bowl is clamped on the clamping head; the bowl bottom of the oil bowl is lower than the outer end of the bearing inner ring; the top end of the outer side wall of the oil bowl is clamped with the clamping head through a transverse clamping part; the inner side wall of the oil bowl is provided with a baffle located at the inner side of the sealing component main body through a transverse connecting plate; the top end of the baffle projects out of the inner end of the sealing component main body; and the bottom end of the baffle is provided with a tenon embedded in the bearing inner ring. The problems that after the existing bearing sealing component is used for long time, dust and oil dirt easily enter and the oil dirt is easily thrown away in the running process of a bearing can be solved.
