Abstract
A bearing race ring, especially for high-speed applications, e.g. in jet engines, turbines and high-speed power plants, comprises an annular metallic body formed along one of its inner or outer surfaces with axially extending grooves which are inclined to the axis of the ring. Preferably each groove begins at a level at which an adjacent groove terminates and the angle which the groove makes with the longitudinal axis is defined by the formula tan .alpha.=d.multidot..pi./n.multidot.b wherein .alpha. is the aforementioned angle, d is the diameter of the surface provided with the groove, n is the number of grooves and b is the width of the ring.
