PROBLEM TO BE SOLVED: To provide a rolling device which can obtain wear resistance and seizure resistance which are more excellent than a conventional art even in a use environment which is severe in use under such an abrupt acceleration/deceleration drive condition that the rolling device is accelerated up to tens of thousands of rotation from a static state within one second, and is returned to the static state after several seconds.SOLUTION: At least one of an inner ring raceway surface and an outer ring raceway surface, and a rolling body transfer surface are in a relationship of Rk≤0.103 μm, or one or both of at least one of the inner ring raceway surface and the outer ring raceway surface, and the rolling body transfer surface are in a relationship of Rku≤23.3. |
