Wave spring

A wave spring comprising:

• 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,
• wherein the wave spring is manufactured from a continuous flat wire that forms both the axially resilient spring section and the radially resilient spring section, wherein the flat wire is rotated at a transition from the axial spring section to the radial spring section.

A bearing assembly comprising:

• a bearing unit having an outer ring and an inner ring configured to rotate with respect to each other, and
• a wave spring disposed on the outer ring or on the inner ring, the wave spring including an axially resilient spring section having 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,
• wherein the radially resilient spring section interacts with the inner ring or the outer ring to secure the wave spring to the bearing unit.
