The invention applies to the area of rolling-body cages made of engineering moulding compositions (plastics). This invention eliminates the technical problem of high internal fitting forces of rolling bodies, predominantly rollers and needles, in rolling-bearing cages. This is performed by the inner holding strips (8) in the rolling-bearing cage (1), which are intended to hold the rolling body (2) internally against dropping out, being of a resilient design due to special undercuts (11), which are moulded by cams (10) on the core (9) of the injection mould. As a result, the rolling bodies can be fitted with significantly reduced internal forces into the bearing cage by snapping-in and, at the same time, are held reliably against falling out. Requirements for enveloping circles which are intended to ensure rolling-body, outboard or inboard guidance of the cage can be met in any event by virtue of the high precision which can be achieved. <IMAGE>
