Beschreibung
Zusammenfassung:	FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to mechanical engineering, namely to rail and other types of transportation. A roller bearing comprises an outer and inner rings and rollers taking radial load and a ringless ball bearing taking axial load. Radial clearance in the ball bearing is chosen according to the following formula where rg - radius of the ball bearing race, ds - ball diameter, Deltar - roller bearing radial clearance, beta - contact angle in the ball bearing. Toroidal races of the ringless ball bearing are made in the central part of the roller paths in the roller bearing rings. ^ EFFECT: increasing working efficiency of the bearing and decreasing its weight and dimensions. ^ 2 cl, 2 dwg
