Abstract
The radius of curvature r , r of the cross-sectional shape of an inner ring raceway is made smaller at a central portion and larger at end portions . A contact ellipse at the end portions is made small by increasing the radius of curvature r of the end portions to thereby secure an allowable moment load. In contrast with this, an angular gap is reduced by reducing the radius of curvature r of the central portion
