Abstract: An improved friction part for a frictionally operating device includes friction lining pieces, which are spaced apart from each other by grooves in order to create a friction surface in the form of a circular-ring-shaped disk, especially in respect of suitability for production and/or functionality. In an example embodiment, the friction part has friction lining pieces, which are spaced apart from each other by grooves in order to create a friction surface in the form of a circular-ring-shaped disk, if some or all of the friction lining pieces are in the shape of triangles. The triangular friction lining pieces may be arranged in a plurality of circumferential rows. The grooves between the friction lining pieces may extend as far as a carrier element. Virtually waste-free usage of the linings is thereby possible. A carrier plate can be used as a carrier element, for example.
