摘要： The roller bearing 10 comprises a plurality of rollers 15 which are respectively interposed between a concave-shaped race surface 12 formed on an outer race 11 and a concave-shaped race surfaces 14 formed on an inner race 13. Each of the rollers 15 is structured such that the central portion of the rolling surface thereof is formed by a first convex-shaped bus 17 which corresponds to the concave-shaped race surfaces 12 and 14, while the two end portions of the rolling surface thereof are respectively formed by second buses 16 which have a radius of curvature smaller than the radius of curvature of the first bus 17.

摘要： A sphere is supported in a floating condition by a pneumatic bearing so as to be rotated by compressed air sprayed from a nozzle. The sphere has a single point magnetized on its surface, and is placed on its rotating axis. If the sphere has a dynamic imbalance, the single point is subjected to pressesion around its inertia axis, the locus and displacement velocity of which are measured by the Hall elements arranged in an arc line around the pneumatic bearing, thereby obtaining the dynamic imbalance of the share.

摘要： In the roller bearing, plural of rollers 15 are interposed between an outer raceway 11 of an outer race 12 and an inner raceway 13 of an inner race 14, and a collar portion 16 is formed along one of the axial-direction end portions of the inner raceway 13. The central portion of one of the outer race and inner raceways 11, 14 and the opposing outer peripheral surface of the roller 15 is formed of a first bus with a given radius of curvature. The two end portion sides adjacent to the central portion are formed of a second bus with such a radius of curvature that causes the two end portion sides to part away from the other. The collar surface 19 of the collar portion 16 contacting with an end face of the roller 15 being a convex-shaped spherical surface is formed as a concave-shaped spherical surface.
