The utility model discloses a double-row angular contact ball bearing. A bearing outer race (1) is provided with a first lubricant hole (4) and a second lubricant hole (5), the outer orifice of the first lubricant hole (4) is located on the outer wall of the bearing outer race (1), and the inner orifice of the first lubricant hole (4) is located on the inner wall of the bearing outer race (1) and between a first row of steel balls (2) and a second row of steel balls (3); the outer orifice of the second lubricant hole (5) is located on the outer wall of the bearing outer race (1), and the inner orifice of the second lubricant hole (5) is located on the inner wall of the bearing outer race (1) and between an oil seal (7) and the second row of steel balls (3). Since the two lubricant holes are machined on the bearing outer race, the splashing machine oil in a gearbox can enter the bearing, so that the grooves and the oil seal of the bearing can be lubricated, and the double-row angular contact ball bearing has the characteristics of ingenious design, simple structure, reliable performance and the like, and is easy to machine and produce.
