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

The tapered-roller bearing has an inner race formed with a groove having a frustoconical base on which is provided an array of rollers that also engage a frustoconical surface on an outer race. A cage comprising a ring lies on one of the ledges defining grooves in the inner race and has a plurality of spacer elements engaged between the rollers and formed with ledges overreaching the groove-forming ridge of the inner race and preventing axial displacement in one direction by engagement of the bases of the pockets formed between the spacer elements with the wide ends of the tapered rollers. The spacer elements are formed at their ends distant from the ring body with enlarged heads fitted to the tapered rollers and holding them in place on the inner race.
