La tête de rouleaux d'appui (14) est pourvue de deux rouleaux d'appui (21, 22) à axes parallèles et la tête de rouleaux de cylindrage (13) est dotée de deux rouleaux de cylindrage (23, 24) qui s'engrènent dans les rayons ou les gorges des tourillons des paliers principaux (6) ou des paliers de course (5) des vilebrequins (3). L'invention est caractérisée en ce que, lorsque le dispositif de cylindrage (8) est configuré à la manière d'une paire de ciseaux, la tête de rouleaux de cylindrage (13) est équipée d'un rouleau de guidage axial (27) disposé au centre de la tête de rouleaux de cylindrage (13). L'axe de rotation (7) de ce rouleau de guidage axial est perpendiculaire à l'axe de rotation (4) du vilebrequin (3), son diamètre (28) étant légèrement inférieur à l'espacement (29a) entre les films d'huile (25, 26) d'un tourillon de palier principal (6) ou de palier de course (5) du vilebrequin (3).
