Abstract
A roller cage for a rolling bearing, particularly a double roller cage for a cylinder rolling bearing, which has a ring web with axially extending webs. Every two adjacent webs delimit a receptacle pocket for a rolling element with a floor thereof being formed by the ring web. Each web has a radial outer and inner base side connected to each other by an axial outer face side. The face side of the radial outer base side is tapered toward the radial inner base side. To increase the rigidity of the webs with regard to trouble-free removal and installation of the rolling bearing, the radial inner base side is trapezoidal such that a web width of the radial inner base side increases from the face side to the floor of the receptacle pocket.
