To measure the radial runout of a rolling bearing such as a cylindrical roller bearing, the outer ring or inner ring is fixed so that an appropriate radial load is applied to the bearing, and the measuring probe is placed at the center of the inner diameter surface of the inner ring or the outer diameter surface of the outer ring. , measure the radial run-out of the inner ring or outer ring by applying it in the direction that corresponds to the radial load, or place the inner ring on a horizontal mandrel and apply the probe at the center of the outer diameter surface of the outer ring in the direction that corresponds to the radial load. are being measured. In the latter measurement, traditionally, a radial load is applied from above to below the bearing, or the outer ring's own weight is applied as a radial load, and the upper half of the bearing is set as the load zone, and the measuring head is applied to that area. radial runout was being measured.

In addition, the applicant has recently discovered that the most suitable measurement method for measuring the radial runout of rolling bearings, such as double-row spherical roller bearings, is to install the inner ring with its central axis horizontally, and to measure the bearing from below the outer diameter surface of the outer ring. A pair of rollers with outer peripheral surfaces parallel to the central axis of the bearing are used to press vertically upward, and the end faces of the inner ring and outer ring are parallel on a vertical plane, and a radial load is applied upward to make the lower half of the bearing the load zone. proposed a measuring device that measures radial runout by applying a probe to the relevant part.

By the way, as mentioned above, in both cases where the upper half of the bearing is measured as the load zone and the lower half of the bearing is measured as the load zone, the inner ring raceway surface and outer ring transfer surface of the bearing are It is important to apply the radial load so that the two are parallel to each other in order to obtain stable and highly accurate measurement values. However,
If the center axis of the bearing is not horizontal due to an installation error of the bearing on the measuring machine, and the inner ring transfer surface and outer ring rolling surface are not parallel, use a load roller held horizontally to measure the outer diameter surface of the outer ring upward or downward. In the case of a double-row spherical roller bearing, when a radial load is applied from
When the load roller contacts the outer diameter surface of the outer ring, due to the self-aligning property of the bearing, the outer diameter surface of the outer ring and the outer circumferential surface of the load roller become parallel, and an equal load is applied, which may adversely affect the measurement results. However, in cylindrical roller bearings that do not have self-aligning properties, the outer diameter surface of the outer ring and the outer circumferential surface of the load roller are not parallel, and an uneven load is applied to the inner ring transfer surface, roller rolling surface, and outer ring roller. The contact of the running surface was uneven, and stable and correct measurement values could not be obtained.

In view of the above-mentioned conventional problems, this invention has been improved and eliminated, and the load roller that applies the load to the outer ring is provided with alignment properties so as to avoid applying an uneven load to the outer ring.
