A brake caliper for a disk brake is disclosed. The brake caliper includes a caliper housing defining a bore that extends along a bore axis. A piston of an actuating device is mounted within the bore so as to be movable along the bore axis in an application direction and a return direction. A sealing arrangement is at least partially provided between the piston and the bore. The sealing arrangement includes a sealing ring positioned in a radial groove. A base surface of the groove is formed in the direction of the bore axis and oriented antiparallel with respect to the bore axis such that the groove base surface approaches the bore axis in the application direction.
