<p>PROBLEM TO BE SOLVED: To provide a rolling bearing capable of relaxing the stress concentration due to a contact of a chamfer part of a bearing and a bearing fitting surface at the time of fixing the rolling bearing to a housing or a shaft and capable of realizing the excellent bearing assembly and the application of the axial preload. SOLUTION: A crowning shape formed of a smooth continuous curved surface is formed between the inner diameter surface of an inner ring of a rolling bearing and at least one inner ring end surface and/or a flat part 10a as an outer diameter surface of an outer ring 10 and at least one outer ring end surface 10f. Since an edge is not formed in a chamfer part 10m at a starting part thereof, stress concentration due to a contact with the bearing fitting surface is relaxed, and generation of damage is previously prevented.</p> |
