A radial rolling-bearing testing device includes a housing, a lubricant reservoir provided inside the housing and configured so as to retain lubricant in which a portion of a radial rolling bearing is immersed, a rotary shaft which is supported so as to freely rotate inside the housing and which an inner ring of the radial rolling bearing is fitted outside, a rotational driving section which is configured so as to rotate the rotary shaft, a load applying section which has a pressurizing device and is configured so as to apply a load to the radial rolling bearing, and a vibration sensor configured so as to detect a vibration in the radial rolling bearing. The vibration sensor is provided on an outside of the housing, and between the pressurizing device and the radial rolling bearing in a direction in which the load applies. |
