1. A centrifugal pendulum device, comprising:
at least one flange;
at least one centrifugal weight disposed displaceably on the at least one flange, the at least one centrifugal weight being guided displaceably on the at least one flange by roller elements;
the flange having openings with guide tracks arranged radially on a radially outer side thereof;
the at least one centrifugal weight having two side elements with guide rails arranged therebetween with weight guide tracks, the guide rail of one said centrifugal weight being inserted into one of the openings of the flange, the weight guide tracks being arranged radially inside the guide tracks of the flange so that the guide tracks of the flange and the weight guide tracks are arranged to oppose each other at a same axial height in a radial direction and the roller elements are arranged therebetween in the radial direction;
the openings in the flange include at least one first opening configured for damping a first rotary vibration order and having first ones of the guide tracks, and at least one second opening configured for damping a second rotary vibration order and having second ones of the guide tracks; and
the guide rail of the at least one centrifugal weight is inserted into one of the first or the second opening that is assigned to a selected one of the first or second rotary vibration orders to be damped.
