The gap dimension C between the race or other protrusions formed thereon, the amount of deformation due to the operating load rating of the rolling element is δ1, and the amount of deformation due to the static load rating is δ.
2. A bearing characterized in that the dimension satisfies δ1+δ3<C<δ2+δ3, where δ3 is the gap formed between the rolling element and the outer race when no load is applied.
