Abstract
Balls are supported between the spherical inner race (5) and the outer race (6) which surrounds one potion of the inner race (6)through the resiliently transformable shell-like retainer (7). By making the inner race (5) and outer race (7), which influence the bearing precision greatly, to be formed in a unit respectively, the bearing precision is increased. For reference, although the retainer is divided, the retainer (7)bears merely the ball holding function and its transformation and the position relation in assembling state do not influence the bearing precision.
Claims11
A free spherical ball bearing comprising balls to be supported through a resiliently deformable retainer between a spherical inner race and an outer race surrounding one portion of the inner race in a unitary matter, the retainer being configured shell-like and formed by being divided at least at one portion.
A free spherical ball bearing comprising:
- balls supported by a resiliently deformable retainer between a spherical inner race and an outer race surrounding one portion of the inner race in a unitary manner;
- a ball receptor that receives the balls by deforming resiliently;
- and
- a grease receptor that receives grease.
