1. A rotary bearing (50) for harmonic gearing, comprising:
rolling elements (8);
an outer bearing ring (1b) defining a bearing surface (9) and an inner bearing ring (1a) defining a bearing surface (7), with the inner bearing ring (1a) arranged in the outer bearing ring (1b), wherein the inner bearing ring (1a) and the outer bearing ring (1b) are each provided with at least one receptacle (10, 11) through which, when the two receptacles (10, 11) are in a corresponding position with respect to each other, the rolling elements (8) are insertable through a receptacle opening (22) formed by the two receptacles (10, 11) into an anti-friction bearing between the bearing surface (7) of the inner bearing ring (1a) and the bearing surface (9) of the outer bearing ring (1b); and
a guide ring (20) arranged in at least one of the two receptacles (10, 11) between the receptacle opening and the rolling elements (8), said guide ring (20) having an annular projection (41) that runs axially and is configured for contacting the rolling elements (8).
