The invention relates to a pin cage for large radial or axial roller bearings. The pin cage has axle pins between spacing bolts. The axle pins being retained in axial bores in the annular disks. The roller bearing elements are rotatably mounted on the axle pins. The pin cage is a structural unit which is preassembled separately from the roller bearing elements and has free minimum distance between all roller bearing elements at the level of the graduated circle of the axial bores for the axle pins, the diameter of the graduated circle of the axial bores for the spacing bolts being smaller or larger than the diameter of the graduated circle of the axial bores for the axle pins. The axle pins for the roller bearing elements are cylinder pins which are inserted into the axial bores of the preassembled structural unit from the outside.
