ABSTRACT:
A ball bearing has an outer ring and an inner ring with respective rolling tracks for a set of balls, the ball bearing being of the so-called "oblique" type in which the rolling tracks, in section, constitute arcs of a curve the normal to which at the mid point of the curve is inclined at a predetermined angle with respect to the axis of the rings. Adjacent the rolling track on the inner ring is a groove the minimum diameter of which is less than that of the rolling track and adjacent the rolling track of the outer ring is a cylindrical surface the diameter of which is less than the maximum diameter of the rolling track. The difference in diameters between the cylindrical surface and the minimum diameter of the groove is such that half this difference is equal to the diameter of a ball.
