A method for packing rolling elements in a bearing providing using a bearing ring fixing component to fix a first bearing ring, preventing it from shifting when subjected to radial compression; inserting two first packing supports between a first bearing ring raceway and a second bearing ring raceway at a predetermined circumferential angle, the two first packing supports dividing the bearing in a circumferential range into a compression zone lying and a warping zone lying outside the range of the circumferential angle; and using a bearing ring compression component to apply a compressive load to a circumferential portion of the second bearing ring. The compressive load directed towards the first bearing ring in a radial direction, to force a radial gap between the first bearing ring raceway and second bearing ring raceway to decrease, such that a window suitable for packing the rolling elements is formed in the warping zone.

A method for producing a composite rolling bearing (1) having a bearing flange (3) and at least one rolling bearing (4, 5) held on the bearing flange (3) by an inner ring (6, 7). In order to be able to fix the inner ring (7) on the bearing flange (3) with axial preloading without expansion, the inner ring (7) is acted upon by a holding-down device (23) that radially holds down the inner ring (7) and is preloaded against the inner ring (7) by a regulated axial force (F), and, by way of an advancing cone (21) introduced radially on the inside axially into the bearing flange (3), material (11) present on the bearing flange (3) is displaced radially towards the outside into a recessed formation (15, 16) in the inner ring (7).

A method of manufacturing a rotating bearing unit includes to cause one end surface in the axial direction of the forming punch (46), formed by combining a plurality of punch elements (46, 46) divided in the circumferential direction, which are displaceable in the axial direction and which are not displaceable in the circumferential direction, and having a processing teeth (44, 44) at one end surface in the axial direction, to face the other end surface of the caulking section (20) in the axial direction. In this state, rolls (30a) are rotated about the central axis (α) of the hub main body (8) while pressing the other end surface of the forming punch (46) in the axial direction with a pressing surface (43) of the roll (30a) having a central axis (β) that is inclined with respect to the central axis (α) of the hub main body (8).

A boot needle roller bearing is designed to reduce friction between a flexible boot non-rotatably attached to a differential housing and a rotatable half-shaft. A plurality of rollers is retained axially between a first lip formed in the outer ring and a set of protrusions that are formed after installation of the rollers by bending prongs inwardly. The inner ring is retained axially between the protrusions and a second lip formed into the outer ring after installation of the inner ring.

Tapered roller bearings and methods of producing the same are disclosed. One method is for producing an inner ring for a tapered roller bearing in which the inner ring comprises a raceway portion and a fixed edge portion. The method may include providing an inner ring blank and an unfinished fixed edge portion. The inner ring blank may include an unfinished raceway portion and the unfinished fixed edge portion may have a larger outside diameter than the unfinished raceway portion. The inner ring blank may have a through-opening. The inner ring blank may be formed into the inner ring by extrusion in a main forming step, the unfinished fixed edge portion being transformed into the fixed edge portion and the unfinished raceway portion being transformed into the raceway portion. The inner ring may be formed in its final contour without any cutting.

A method is disclosed for producing a tapered roller assembly which can be mounted in a particularly simple manner. For this purpose, a method for producing a tapered roller assembly having an inner ring and a roller ring is proposed, wherein the method comprises the following steps: a) providing the inner ring , wherein the inner ring has a flanged mounting rim which is produced within a preliminary flanging stage by flanging over an edge region of the inner ring; b) mounting the roller ring on the inner ring, wherein the roller ring is pushed over the flanged mounting rim onto the inner ring; c) flanging over the flanged mounting rim into a flanged rim wherein the flanged rim, as a retaining rim, captively retains the roller ring; and d) heat treating the flanged mounting rim before step b) or step c), wherein a hardness of the flanged mounting rim is reduced by comparison with a hardness of a raceway of the inner ring. Also proposed is a tapered roller bearing formed with such a tapered roller assembly.
