Abstract
The socket is made with a bowl having a spherical cap in the polar region and a part-spherical section which extends from the spherical cap on a larger diameter. The two sections join together at a distance from the top of the bowl socket which is 1/3 the diameter of the spherical cap while the diameter of the part-spherical section is from 1.02 to 1.10 times the diameter of the spherical cap. The diameters of the spherical cap and the part-spherical section intersect the axis of symmetry of the socket body, one on the equatorial plane and the other below the equatorial plane.
