Analytical relationships have been developed for the design of modified tapered roller bearings based on standard bearings of the 7000 type. The modification consists in replacing the rolling elements in the form of tapered rollers with a straight generatrix by concave rollers with an arc generatrix, which are in contact with the convex raceways of the rings. By calculation, the advantage of modified roller bearings in terms of service life in comparison with standard roller bearings of similar overall dimensions is shown.
