PROBLEM TO BE SOLVED: To provide a combined rolling bearing increasing a sealing amount of a lubricant and preventing leakage of the lubricant from bearing abutting sides. SOLUTION: End surfaces of inner rings 2 are directly abutted, on the abutting sides of two angular ball bearings 1, an annular sealing member 8 is inserted across a recessed stepped part 7 formed in the peripheral surface of each outer ring 3 to seal the abutting sides of the bearings, and sealing members 6 sealing portions between the inner rings 2 and outer rings 3 are mounted only on the opposite sides to the abutting sides. Thereby, the sealing amount of the lubricant to a common bearing space is increased, and there is no risk of leakage of the lubricant from the abutting sides of the bearings.
