The invention relates to a transmission component set comprising a bearing ring (1) and a harmonic drive transmission, which can be mounted thereon. Said harmonic drive transmission comprises a drive component (2), a resilient transfer component (4) having an external toothing (3), and a gear (6) having an internal toothing (5), wherein the transfer component (4) can be fitted onto the drive component (2) and thereby is elliptically deformable in such a way that the external toothing (3) of the transfer component (4) can be brought into engagement with the internal toothing (5) of the gear (6) in opposing regions of a large ellipsoid axis of the gear (6), wherein the gear (6) or the transfer component (4) having a bearing surface (7) can be mounted on a bearing surface (9) of the bearing ring (1) by means of rolling elements (8), characterised in that the gear (6) or the transfer component (4) and the bearing ring (1) are in each case provided with at least one receptacle (10, 11), by which in a corresponding position of the two receptacles (10, 11) relative to one another rolling elements (8) can be introduced into a rolling bearing between the bearing surface (7) of the gear (6) or of the transfer component (4) and the bearing surface (9) of the bearing ring (1).
