Patent ID: 8047723

Claim:
Radial anti-friction bearing, comprising a single-row spherical roller bearing that includes an outer bearing ring and an inner bearing ring and a plurality of spherical rollers that are arranged between the bearing rings and that are held at uniform distances from each other in a peripheral direction by a bearing cage and each of the spherical rollers have two side surfaces flattened symmetrically from a spherical base shape and arranged parallel to each other and roll with running surfaces thereof defined between the side surfaces in two groove-shaped raceways formed in an inside of the outer bearing ring and in an outside of the inner bearing ring, wherein the raceways are each defined by two axial rims, respectively, wherein a width of the spherical rollers between the side surfaces is less than a distance between the radially opposing, axial rims of the raceways in the bearing rings and the spherical rollers thus can be inserted through this distance in an axial mounting method into the radial anti-friction bearing, the radial anti-friction bearing has an axial load capacity that is suitable for variable axial loads under an operating pressure angle of up to 20° on both sides of a bearing longitudinal axis with the running surfaces having 100% contact with the raceways, and the width of the spherical rollers between the side surfaces is arranged for an operating pressure angle of 20°.
