A method of making a rotationally symmetric body, particularly an annulus ( 1 ) for a planet gear carrier, said annulus comprising a tooth profile ( 2 ) and/or additional elements ( 3 ), and said method being a non-cutting shaping method comprising: working the tooth profile ( 2 ) and/or the additional elements ( 3 ) into a sheet metal strip ( 4 ), cutting the strip of sheet metal ( 4 ) into desired lengths before or after working in the tooth profile ( 2 ) and/or the additional elements ( 3 ), bending round the sheet metal strip ( 4 ) to form a rotationally symmetric body and fixing the ends of the strip of sheet metal strip( 4 ) to each other.
