To provide a rolling bearing device capable of equalizing external force applied to a rolling bearing, reducing change of prepressure, or change of rigidity, and achieving low cost.
In this rolling bearing device 10, a rolling bearing 12 is engaged with an outer circumferential surface 11A of a shaft member 11, and an E block 15 is rotatably supported by the shaft member 11 through the rolling bearing 12. The rolling bearing device 10 has a step part 22 for the rolling bearing 12 to be engaged in the E block 15. A split 17 is provided in the E block 15 to face the step part 22. One side part 18 of the split 17 is tightened to the other side part 19 by a bolt 20 to narrow an interval S1 of the split 17, so that an inner circumferential surface 22a of the step part 22 is pressed to the rolling bearing 12.
