Abstract
A radial bearing configured as a single-row spherical roller bearing is provided that includes an inner and outer bearing ring, and rollers arranged between the bearing rings. The rollers have two side faces which are flattened symmetrically from a spherical base shape, and roll in two groove-shaped raceways which are defined by two axial rims. The width of the rollers between their side faces is at least 70% of the diameter of the spherical base shape and is greater than the distance between the axial rims. The rollers are in full linear contact with their running faces in the bearing rings at an operational pressure angle of up to 25° on both sides of the bearing longitudinal axis. The distance between radially opposite axial rims when the bearing rings are arranged eccentrically to each other is less than the diameter of the spherical base shape of the rollers.
