Abstract

A wave spring having an axially resilient spring section including at least one one-layer wave-shaped spring configured to provide a spring force in an axial direction of the wave spring, and a radially resilient spring section configured to provide a spring force in a radial direction. The wave spring may be made from a continuous flat wire that forms both the axially resilient spring section and the radially resilient spring section, the flat wire being rotated 90° at a transition from the axial spring section to the radial spring section.
