La selle d'appui (12) se caractérise en ce qu'il est prévu au moins une couche de billes (48) entre la partie destinée à recevoir la charge (16) et la partie d'appui (18), et qu'il est également prévu, de préférence, au moins un moyen d'ancrage (50) qui autorise des erreurs d'alignement ou des mouvements relatifs dans des limites prédéfinies, tout en empêchant que la partie destinée à recevoir la charge (16) et la partie d'appui ne se scindent accidentellement.
