Abstract
A labyrinth seal includes a first labyrinth ring and a second labyrinth ring. In an installed state of the labyrinth seal, the first labyrinth ring and the second labyrinth ring engage in each other in an at least partially overlapping manner and are rotatable relative to each other. Furthermore, in the installed state, mutually-opposing surfaces of the first and of the second labyrinth ring have different wear resistances.
