| description | Provided is a rolling bearing that can both ensure durability and reduce rotational resistance. The rolling bearing includes a seal member that is mounted on an outer ring and that covers a space between an inner ring and the outer ring from an outer side in an axial direction, and grease disposed between a rolling element and the seal member. The seal member includes an annular pedestal portion in contact with the outer ring from an outer side in the axial direction, an extending portion that extends outward in the axial direction from an inner peripheral edge of the pedestal portion, and a flat surface portion that extends along a radial direction from an end edge of the extending portion on an outer side in the axial direction toward the inner ring. The grease includes an outer ring contact portion in contact with an inner peripheral surface of the outer ring, and a seal member contact portion in contact with the flat surface portion on an outer side in the axial direction and an inner ring side with respect to the outer ring contact portion. An area of the seal member contact portion is larger than a contact area between the grease and the extending portion as well as the pedestal portion of the seal member. |
