Axially spaced radial bearing units (30, 50) for a shaft assembly are pre- loaded by hydraulic pressure. Each of the bearing units is mounted to an axially displaceable seat (40, 60). The pre-loading pressure between the two bearing units (30, 50) is maintained at a constant pre-loading pressure by a hydraulic pressure which is exerted in chambers (44, 64) partially defined by the seats. A pressure accumulator (70) supplies pressure to the chambers (44, 64) so that a constant pre-loading pressure may be applied to the radial bearing units (30, 50) while allowing for axial displacement of the bearing units and the shaft (12).
Des ensembles palier radial espacés axialement (30, 50) pour un ensemble arbre sont préchargés par pression hydraulique. Chacun des ensembles palier radial est fixé sur un siège déplaçable axialement (40, 60). La pression de préchargement entre les deux ensembles à palier radial (30, 50) est maintenue à une pression de préchargement constante par une pression hydraulique qui est appliquée dans des chambres (44, 64) partiellement définies par les sièges. Un accumulateur de pression (70) fournit de la pression aux chambres (44, 64) de sorte qu'une pression constante de préchargement puisse être appliquée aux ensembles palier radial (30, 50) tout en permettant un déplacement axial des ensembles palier radial et de l'arbre.
