Abstract
A rolling bearing, wherein the rolling elements are loaded, equipped with a cage separating the rolling elements, wherein at least one groove is situated on the bearing race on which the rolling elements travel, wherein edges of the groove are positioned at an angle α from 4.5° to 80° in relation to the movement direction of the rolling elements, and in the cage, holes for the rolling elements are made askew so that the angle β between a straight line connecting the cage centre with the centre of the hole for the rolling element and a tangent to the rolling element in the contact point of this element with the cage has a value β>arc tg μ, where μ is the sliding friction coefficient of mating of the rolling element material with the cage material.
