A bearing device includes a pair of bearings. One of the bearings is exposed to a higher temperature condition than the other. Each of the bearings has an outer ring, an inner ring, a plurality of rolling members disposed in a space between the outer ring and the inner ring and a pair of sealing members fixed to the outer ring. Each of the sealing members has an elastic lip in contact with an outer surface of the inner ring, and the lip of the bearing exposed to a higher temperature condition is made of a material that is more heat-resistant than the lip of the other sealing member.
