Abstract
The radial antifriction bearing has an outer bearing ring, an inner bearing ring and roller bodies, which are arranged between the bearing rings, are held at uniform distances from one another in the peripheral direction by a bearing cage. The roller bodies are discs that each have two parallelly arranged lateral surfaces which are symmetrically flattened from a spherical basic shape. In order to prevent edge stresses between the discs and the raceways, at least the raceway in the inner bearing ring, on its outer edge areas, transition into a logarithmically decreasing profile.
