A rotor member is described for a gas turbine that is adapted for rotating about a central axis, the rotor member being a blisk having a rotor blade row that extends around the central axis or a rotor disk having a mounting portion for installing rotor blades of a rotor blade row that extends around the central axis, and being axially offset from the rotor blade row and/or the mounting portion and, extending coaxially, having at least one annular and axially asymmetrical sealing fin that has a radially outer tip portion having a front flank facing the rotor blade row and/or the mounting portion, and an opposite flank facing away from the rotor blade row and/or the mounting portion; the front flank being less steep than the opposite flank; a turbine and a compressor having such a rotor member, and a method for manufacturing such a rotor member having at least one sealing fin coating.

A rotor stage () for a turbomachine, including a plurality of rotor blades (), a rotor main body () having at least two rotor arms () and a balancing assembly () for balancing the rotor stage (). The rotor arm () configured downstream from the rotor main body () features the balancing assembly (). The balancing assembly () is configured between the axial end region of the rotor arm () and the rotor disk () of the rotor main body (). Furthermore, a rotor drum () for a turbomachine and a rotor () for a turbomachine.
