1. A roller freewheel having an axis of rotation for a torque transmission depending on a direction of rotation, comprising:
a roll body cage;
a plurality of roll bodies, the roll bodies being housed in the roll body cage; and
a ramp ring having a ramp contour for blocking the roll bodies with the ramp contour in a first direction of rotation and for allowing rotation of the roll bodies relative to the ramp ring in an opposite, second direction of rotation,
wherein: the ramp contour of the ramp ring is designed to house a plurality of roll body rows;
the roll body cage comprises a plurality of separate identical partial cages, each identical partial cage comprising at least one roll body row; and
the ramp ring is produced by deep drawing.
