Abstract: The present disclosure relates to a double-structure bush usable in a joint portion which operates in low speed and high load, and to a bearing assembly comprising same.

Abstract: A bearing shell for a sliding bearing may include a body having a convex outer surface and an alignment feature projecting from the outer surface. The alignment feature may be arranged at an end face of the body. The alignment feature may include a first tapered portion having an axial width that reduces in a direction away from the end face. The first tapered portion may include at least two axial sides extending circumferentially and angled away from parallel with respect to a corresponding axial end face of the body by an angle of 2° to 10°.

Abstract: A method of forming a hybrid component comprising at least two metallic parts, the method comprising preparing a first metallic part by forming at least one macroscopic interfacing feature on an interfacing surface of the part; positioning the first part in a mould tool; introducing a metallic powder into the mould tool and around the interfacing feature(s); and consolidating the metallic powder by a Hot-Isostatic Pressing (HIP) process to form a second metallic part which encapsulates the interfacing feature(s) to provide a mechanical connection between the first and second parts of the component. Also, a hybrid component so formed. The metallic parts may have substantially different material properties.

Abstract: In a cold rolling method for producing annular composite workpieces, at least two hollow cylindrical workpieces made of different materials are inserted into one another. The at least two hollow cylindrical workpieces are roll formed by pressing the at least two hollow cylindrical workpieces against each other between two diametrically opposed external roll forming tools and an internal rolling arbor or between two diametrically opposed external roll forming tools and an internal roll forming tool to form a composite workpiece. The composite workpiece is a bearing ring or a gear ring. One of the hollow cylindrical workpieces can be a nonferrous material such as aluminum.

Abstract: A bearing, particularly a rubber bearing, has in its fundamental structure at least one bearing bushing and one rubber body surrounded by the bearing bushing. The bearing bushing has at least one longitudinal parting line having edge profiles that are complementary to one another, provided at adjacent longitudinal edges. The tines and tine recesses, respectively, engage into one another at the edge profiles which are complementary to one another. The tine along the one longitudinal edge, in each instance, dips into a related tine recess on the other longitudinal edge, essentially in the circumference direction of the bearing bushing in the course of production. During this process, the tine is plastically deformed by a predetermined measure, so that the tine and the related tine recess wedge into one another.

Abstract: A lined and flanged bush and method of manufacturing the same comprising: providing a liner having an aperture; locating the aperture in the liner around the spigot such that the liner lies on the surface; and stamping out the blank around the spigot to provide a lined and flanged bush.

Abstract: A bushing utilizes a fabric reinforced thermoset composite sleeve incorporated within an outer shell in a construction enabling the sleeve to be press-fitted within the shell and held therein by a constriction in the shell bore which is embraced by the bearing liner. Following installation of the bearing sleeve, the sleeve bore may be reamed to provide a uniform inside diameter.

Abstract: A lead-free bearing includes a bronze matrix powder metal bearing layer bonded to a steel backing a fully densified. The bearing material has about 8 to 12% by weight tin, about 1 to less than 5% by weight bismuth, and about 0.03 to 0.08% by weight phosphorus, with the balance being copper. The tin is soluable in the copper to yield the bronze matrix, and the bismuth exists as finely dispersed, undissolved islands through the matrix. Such bearings exhibit physical properties comparable to or better than those of traditional bronze-lead bearings and improved wear in seizure properties.

Abstract: A bearing bush that can be installed without any auxiliary components and ensures a secure fit has a backing which comprises at least one layer, an overlay (4), on its inner surface and at least one flange (6, 6a, 6b) in the form of a circumferential closed bead provided at a distance from the bush ends. The bearing bush is suitable, inter alia, for flexible joints and pedal bearing systems. The method of producing such a bush takes as its starting point a prefabricated bearing bush (1), the inner surface of the backing (3) of which is exposed in at least one area (5, 5a, 5b) spaced from the bush ends. An internal mandrel is inserted into the bearing bush (1) and the bearing bush is held around its outer surface, at least one gap (23) being left opposite to the exposed area (5, 5a, 5b). The bearing bush is then compressed in the axial direction, the material is thereby displaced into the gap (23, 23′) to form the flange (6).
