PROBLEM TO BE SOLVED: To provide a rolling bearing having excellent lubrication characteristics.SOLUTION: A rolling bearing 1 includes: an outer ring 2 having an outer ring raceway 2a in the inner periphery thereof; an inner ring 3 having an inner ring raceway 3a opposite to the outer ring raceway 2a in the outer periphery thereof; and a plurality of rollers 4 arranged in a rollable manner between the outer ring raceway 2a and the inner ring raceway 3a. The rolling bearing includes: a flange side surface 2c provided in at least one of the outer ring raceway 2a and the inner ring raceway 3a and extending in a radial direction from both end parts to the other side; and a cylindrical separator 5 provided between two adjacent rollers 4 and having self-lubrication characteristics. In the separator 5, an end surface 5b is arranged so as to approach the flange side surface 2c. |
