<p>A rolling contact device having a shaft (1) adapted to be secured to an element of an apparatus, an outer ring (2) adapted to be in rolling contact with another element of the apparatus, and rolling elements (3) disposed between the shaft (1) and the outer ring (2). An abutting portion (1c)(1d)(2b)(2c) is provided on each of the shaft (1) and the outer ring (2), the abutting portions on the shaft and the outer ring being opposed to each other with a small gap (G) defined therebetween. These abutting portions are arranged such that, when an exessive radial load is applied to the outer ring, the abutting portions are brought into contact with each other to prevent permanent deformation of rolling contact portions of the device.</p> |
