PROBLEM TO BE SOLVED: To provide a rolling bearing for high-temperature environment, capable of preventing a surface damage caused by increase in the internal load even if misalignment between a bearing housing and an angular ball bearing is enhanced by thermal expansion. SOLUTION: A bearing used in a high-temperature environment such as an iron making facility is likely to cause a surface damage such as early spalling when misalignment occurs between a bearing housing 1 and a rolling bearing since the misalignment is enhanced by thermal expansion of the bearing housing or the rolling bearing to increase the internal load. As a countermeasure thereto, two angular ball bearings 3 stowed within the bearing housing to constitute a combination rolling bearing 2 are composed of DF combination. COPYRIGHT: (C)2008,JPO&INPIT
