Abstract

Summary A shaft bearing device with a lifting device The invention relates to a shaft bearing device (1) for a pump (2), wherein the 5 shaft bearing device (1) comprises an antifriction bearing (8, 81, 815), which can be connected to an axially displaceable pump shaft (5). A spring (7, 71, 72) is arranged at the antifriction bearing (8, 81, 815) in such a way, that a spring force (F) can be transmitted to an outer ring of the antifriction bearing (8, 81, 815) by means of the spring (7, 71, 72) in a mounting condition of the shaft bearing device 10 (1). A lifting element (3) attached to the pump shaft (5) and a corresponding counter element (4) are separated from each other by the spring force in a starting state and/or in a shutdown state of the pump (2). The invention further relates to a pump (2) with a corresponding shaft bearing device (1). 15 Fig. 2 Inventor: Wild, Andreas 20
