PROBLEM TO BE SOLVED: To compatibly attain the toughness resistance and machinability of the rolling elements of a rolling bearing.SOLUTION: To solve the above issue, the rolling bearing includes at least an inner ring, an outer ring, rolling elements, and a cage. The rolling elements is each formed of an oxide ceramic composite material containing a first component and a second component having a hardness ratio and a Young's modulus ratio of 1.5-2:1, a fracture toughness value ratio of 1:1.5-2, and a volume ratio of 1-5:5-9. |
