Abstract

La invención se refiere a un dispositivo de rodamiento de eje (1) para una bomba (2), en donde el dispositivo de rodamiento de eje (1) comprende un rodamiento antifricción (8, 81, 815), el cual puede estar conectado a un eje de bomba desplazable axialmente (5). Un muelle (7, 71, 72) está dispuesto en el rodamiento antifricción (8, 81, 815) de tal manera que, una fuerza de muelle (F) puede transmitirse a un anillo exterior del rodamiento antifricción (8, 81, 815) por medio del muelle (7, 71, 72) en una condición de montaje del dispositivo de rodamiento de eje (1). Un elemento de elevación (3) unido al eje de la bomba (5) y un contra elemento correspondiente (4) están separados entre sí por medio de la fuerza del muelle en un estado de inicio y/o en un estado apagado de la bomba (2). La invención se refiere además a una bomba (2) con un dispositivo de rodamiento de eje correspondiente (1).
