Abstract
An anti-friction bearing device comprising an outer ring ( ) provided with an outer surface and a bore on which a toroidal bearing inner race ( ) is formed, an inner ring( ) which is provided with a bore and a cylindrical outer surface on which a toroidal bearing outer race ( ) is formed, a row of balls ( ) which are disposed between the two bearing races, and a cage which can maintain a regular circumferential spacing between the balls. The ratio between the radial thickness of the outer ring, when taken between the bottom of the bearing inner race and the outer surface of the outer ring and the diameter of the balls ranges from 0.4 to 0.7. The ratio between the radial thickness of the outer ring, when taken between the bottom of the bearing inner race and the radial thickness of the inner ring when taken between the bottom of the outer bearing race and the bore of the inner ring ranges from 1.1 to 1.6.
