베어링 장치에 있어서, 내(耐)크리프성과 내전해 부식 성능의 양방을 동시에 실현한다. 내륜(11)의 내직경면(11b)과 외륜(12)의 외직경면(12b) 중 적어도 한쪽이, 코팅층(30)에 의해 덮여 있다. 코팅층(30)이 복수 층으로 이루어진다. 복수 층 중, 표면층이, 윤활성을 갖는 내크리프 피막(31)으로 이루어지고, 표면층을 제외한 적어도 일층이, 절연성을 갖는 절연 피막(32)으로 이루어진다. A bearing device is provided which achieves both creep resistance and electrolytic corrosion resistance. At least one of the radially inner surface (11b) of the inner ring (11) and the radially outer surface (12b) of the outer ring (12) is covered with a coating layer (30). The coating layer (30) is a coating layer composite composed of a plurality of layers. Of the plurality of layers, the surface layer is composed of an anti-creep film (31) having lubricity, and at least one layer other than the surface layer is composed of an insulating film (32) having insulating properties.
