- 該第1の半輪と前記第2の半輪は、該内輪を構成し、更に静止シャフト(104)の周りに摺動可能に取り付けられるように設計される、ことを特徴とする請求項1に記載の軸受。
- 該静止シャフトは、前記スラスト部材を形成する一部を具備する、ことを特徴とする請求項4に記載の軸受。
- 前記第1の予圧システム(120)と前記第2の予圧システム(126)は、それぞれの弾力性のアセンブリを具備する、ことを特徴とする請求項1に記載の軸受。
- 各該弾力性のアセンブリは、1つ以上のばね座金を具備する、ことを特徴とする請求項6に記載の軸受。
- 該転動要素は、斜め接触軸受ボールである、ことを特徴とする請求項1に記載の軸受。
- 前記軸受は、ラジアル流体軸受に搭載された回転機械の軸方向のスラスト軸受に適用される、ことを特徴とする請求項1〜8のいずれか一項に記載の軸受。
