Abstract

A rolling bearing that can easily achieve the higher lubricating characteristic including the smaller rotational torque while employing the existing bearing shape and lubricant is provided. A rolling bearing 1 includes: an inner ring 2 and an outer ring 3 as a race ring; a plurality of rolling elements 4 held between the inner and outer rings; a retainer 5 that retains the rolling elements 4; a sealing member 11 provided at openings on opposite ends in an axial direction of the inner ring 2 and the outer ring 3; and grease 12 to be enclosed in an in-bearing space. At least one member selected from the inner ring 2, the outer ring 3, the retainer 5, and the sealing member 11 is provided with a flocking part 6 formed by flocking fiber on a surface of the member which is in contact with the grease 12.
