Abstract
A rolling bearing apparatus capable of restraining the residence of air bubbles in the water-cooling jacket while curbing the running cost and the production cost is provided. A rolling bearing apparatus is configured to include a rolling bearing, and a housing which houses the rolling and in which a water-cooling jacket into which cooling water is introduced. By forming the bottom portion of the water-cooling jacket by an inclined surface in the axial direction, it is possible to preferably rectify the cooling water in the water-cooling jacket and therefore effectively restrain the residence of air bubbles without increasing the amount of water supplied to the water-cooling jacket.
