Abstract
In a spindle system with a hollow spindle for a linear actuator, the linear actuator has a telescopic tube system including an outer tube and at least one inner tube arranged coaxially with the outer tube and at least partially surrounded by the outer tube. A bearing is arranged to transmit axial forces between the hollow spindle and the outer tube. The hollow spindle at least partially surrounds an inner shaft of the spindle system and is connected to the inner shaft of the spindle system by one or more tappets of a positive and axially displaceable shaft-hub connection. The hollow spindle has a bearing seat for the bearing and an external thread on an outer side.
