PROBLEM TO BE SOLVED: To prolong a usable time further by suppressing a temperature increase of a bearing in a dry-run status. SOLUTION: Friction heating inside the bearing is escaped to a housing 12 through an outer ring 3 by interposing heat conductive grease 6 containing heat conductive material between an outer diameter face of the outer ring 3 and an inner diameter face of the housing 12. Therefore, the temperature increase of a ball bearing 1 in the dry-run status can be suppressed, and the usable time is further prolonged. COPYRIGHT: (C)2008,JPO&INPIT
