A thrust bearing comprises an electromagnetic stator with a stator surface and a rotor disk with a rotor surface facing the stator surface. The rotor disk comprises a radially inner portion made of a first material directly and exclusively connected to a radially outer portion made of a second material. The first material is a corrosion resistant metal or metal alloy and the second material is a ferromagnetic metal or metal alloy.

Method, retention mechanism and bearing device for retaining at least one pad inside the bearing device. The bearing device includes a ring having at least a retaining head, at least one pad disposed inside the ring and having a bottom recess portion configured to receive the at least a retaining head, the at least one pad being configured to pivot on the at least a retaining head, and a retention mechanism configured to retain the at least one pad within a predetermined volume inside the ring. The retention mechanism is configured to apply a retaining force on the at least one pad, in addition to a force between the retaining head and the at least one pad, where the retaining force acts substantially along a radial direction of the ring, away from a center of the ring.
