Patent ID: 8419289

Claim:
Radial anti-friction bearing, comprising a single-row spherical roller bearing that includes an outer bearing ring and an inner bearing ring and also 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 in two groove-shaped raceways formed in an inside of the outer bearing ring and in an outside of the inner bearing ring, the raceways are each defined by two axial rims, respectively, and a width of the spherical rollers between the side surfaces equals at least 70% of a diameter of the spherical base shape and is greater than a distance between the radially opposing, axial rims of the raceways in the bearing rings, the raceways are formed in both of the bearing rings with a depth and width so that the running surfaces of the spherical rollers are in complete linear contact with the raceways in the bearing rings even for variable axial loads under an operating pressure angle of up to 25° on both sides of a bearing longitudinal axis and the distance between the radially opposing, axial rims of the raceways in the bearing rings is less than the diameter of the spherical base shape of the spherical rollers even for the bearing rings arranged in a position eccentric relative to each other.
