A cage-assembling apparatus and method for installing rolling elements (5) such as balls, into pockets (7) of an annular cage (3) is described. The apparatus incorporates a base member (11) for supporting a cage (3) and a rolling-element distributing column (13) disposed concentrically to the cage (3) supported by the base member (11) and permitted to relatively rotate with respect to the base member (11). An opening (28) of a rolling-member supply passage (29) in which a plurality of the rolling elements (5) are loaded in a line is formed at an end of the rolling-element distributing column (13) opposite to the cage (3). Axial-directional (31) or radial-directional (27) are pressing surfaces are formed which forcibly introduce the rolling elements (5) supplied through the opening (28) into the pockets (7) by using relative rotation between the base member (11) and the rolling-element distributing column (13). |
