<p>PROBLEM TO BE SOLVED: To provide a sealed ball bearing of a double seal structure capable of making the width direction of the bearing small, and hard to generate deterioration of seal performance in a case where misalignment is generated between an outer ring and an inner ring.SOLUTION: An erecting part 21 of an outside seal 7 is arranged oppositely to a flange part 12 of an inside seal 6 with respect to an axial direction so that the erecting part has a portion overlapped with the flange part 12 of the inside seal 6 in an axial view. The length of a seal lip 14 of the inside seal 6 is set so as not to protrude to axial outside with respect to an outside surface 12a of the flange part 12.</p> |
