Abstract

To provide a rolling bearing capable of ensuring durability and reducing rotational resistance. The rolling bearing includes an inner ring and an outer ring disposed coaxially with each other; a rolling body disposed between the inner ring and the outer ring; a sealing member mounted on the outer ring and covering a space between the inner ring and the outer ring from an outer side in an axial direction; and grease disposed between the rolling body and the sealing member. The outer ring has an inner circumferential surface facing the inner ring. The inner circumferential surface is formed with an outer ring raceway surface that supports the rolling body in a rollable manner, and a recessed portion that is provided at a location extending in the axial direction from an end edge of the outer ring raceway surface in the axial direction and is recessed in a radial direction. The grease is in contact with the recessed portion.
