<p>PROBLEM TO BE SOLVED: To provide a rolling bearing device capable of easily fitting and positioning a cylindrical roller bearing and an angular ball bearing which are jointly fitted with each other to a rotary shaft, and reducing the machining cost by minimizing the machining of the inside diameter on a housing side. SOLUTION: The rolling bearing device 31 has the cylindrical rolling bearing 33 and the angular ball bearing 36 which are jointly and coaxially fitted with each other. The cylindrical rolling bearing 33 and the angular ball bearing 36 are integrated with each other with inner rings 33a and 36a as a race 38, and are positioned and fixed to the housing by regulating the back side end face differential widthδ3 when the external load Fa in the axial direction is applied to the integrated angular ball bearing 36.</p> |
