Abstract

A flexible metal support device for a rotatable centrifuge rotor (2) provided in a frame member (1) by a bearing member (4). The support device comprises a support element (7) provided between the bearing member (4) and the frame member (1), and arranged to absorb relative movements between the centrifuge rotor and the frame member. The support element (7) comprises an inner mounting portion, essentially immovable in relation to the bearing member (4), and an outer mounting portion, essentially immovable in relation to the frame member (1). Moreover, the support element (7) comprises three flexible connecting portions which each extends between the inner and outer mounting portions and is arranged to absorb radial and axial relative movements between the centrifuge rotor and the frame member. Furthermore, the inner portion, the connecting portions and the outer portion form an integrated unit manufactured in one piece of metal material.
