Abstract
A radial rolling-bearing testing device includes a rotary shaft which an inner ring of a radial rolling bearing is fitted, a rotational driving section which rotates a rotary shaft, a lubricant reservoir which is configured so as to retain lubricant in which a portion of the radial rolling bearing is immersed, and a load applying section which is configured so as to apply a radial load to the radial rolling bearing. A bottom surface of the lubricant reservoir is a curved concave surface which has a partially cylindrical form which is concentric to a central axis of the rotary shaft. An entirety of a housing which supports the rotary shaft may be integrally formed.
