A bearing apparatus includes two split outer ring halves disposed in close contact with each other and a plurality of rollers. A circumferential end of each of the split outer ring halves has a concave-and-convex shape including a first slope portion inclined with respect to a line extending along an axial direction of the split outer ring halves and a second slope portion inclined in an opposite direction to that of the first slope portion. Each of the rollers is provided with crowning so as to be shaped in barrel form, and an amount of crowning is set such that an apex of a projecting portion at the concave-and-convex shape of each of the split outer ring halves is located on an axially outer side of a rolling surface of the roller rolling on an inner peripheral surface of each of the split outer ring halves.
