Abstract
A cage having a plurality of cutouts for receiving rolling bodies of a joint includes a quenched and tempered steel, and the entire cage has a substantially uniform ductility over its cross section without surface hardening. The cage may be produced by forming a closed base body, cutting out a plurality of cutouts, fully hardening the cage by heating and subsequently quenching the cage, and tempering the cage.
