PROBLEM TO BE SOLVED: To provide a bearing device 10 capable of dispensing with preparation of a special jig, suppressing polygonal deformation by uniformly compressing an outer diameter of an outer ring 32, and easily drawing out a housing while reducing damage such as galling.SOLUTION: A rolling bearing 30 is fixed to a fitting hole 52 of a housing 50 by tight-fitting. An outer peripheral face 32b of an outer ring 32 of the rolling bearing 30 is provided with a circumferential groove 35 over the whole periphery, and the housing 50 is provided with an oil hole 55 communicated with the circumferential groove 35 for supplying a pressure oil to the circumferential groove 35.SELECTED DRAWING: Figure 1 |
