Abstract
A method for manufacturing a cage of a polymeric material for a radial rolling bearing with two end rings formed at the cage and arranged at a distance to each other in the axial direction and crossbars spaced behind one another in the peripheral direction connecting the end rings and forming pockets for receiving rolling elements, each crossbar being formed by two relatively thin-walled crossbar walls delimiting the neighboring pockets and a connecting section situated between the crossbar walls, and a device for executing the method.
