A double roller cage for a double-row cylinder roller bearing, with a central ring part (1) from which webs (2, 3) protrude axially on both sides, wherein the webs (2; 3) of one side in each case form a row of bearings (4; 5) together with the rolling bodies arranged therein, wherein every two adjacent webs (2; 3) of a row of bearings (4; 5) delimit a receiving pocket (6; 7) for a rolling body, and in which, at least in one row of bearings (5), the webs (3) are designed so as to taper in the circumferential direction for a radial filling of the receiving pockets (7) with the rolling bearings. So that the double roller cage has satisfactory running behavior and is relatively simple and cost-effective to produce, recesses (12, 12′, 13, 14, 16) are formed on the other of the two rows of bearings (4; 5) in order to produce a symmetrical mass distribution between the two rows of bearings (4; 5).
