The other bearing ring is provided with an elastic bulge having an inner lip that extends upwardly, and forms a sealing portion between the sealing plate and the sealing plate. The outer lip of the tube is in contact with the outer circumferential surface of the circumferential groove, the inner lip is in contact with the inner wall of the circumferential groove, and the circumferential surface between the lips of the enlarged portion has a desired distance between the outer wall and the bottom wall of the circumferential groove. Sealed rolling bearings that face each other with a seal gap of . (2) In paragraph 1 of the claims for utility model registration,
A sealed rolling bearing characterized in that the contact pressure on the outer lip is greater than the contact pressure on the inner lip. (3) In paragraph 1 of the claims for utility model registration,
A sealed rolling bearing characterized in that the contact pressure on the inner lip is greater than the contact pressure on the outer lip.
