Abstract: A radial-axial roller bearing, having an inner ring (5), coaxially with which an outer ring (4) is disposed, between which rolling bodies (15) roll in order to absorb radial forces, and having cylindrical rolling bodies (17, 18) disposed in cages (19, 20, 24, 25) on both sides to absorb lateral forces, the tracks of which are formed on one side by the end faces of the outer ring (4) and on the other side by a runner plate (8, 9) in each case. The inner ring (5) is formed from two part-rings (6, 7), which are integrally connected to the runner plates (8, 9), a separating plane (14) being placed between the part-rings (6, 7) in the track region of the radial bearing (1). In this manner, a compact, tilt-resistant bearing unit is formed.

Abstract: The improved spherical plain bearing of the present invention is formed using a unique method of manufacture which includes surface hardening of the outer ring and the inner ring wherein the outer ring includes a fracture zone having a reduced cross-sectional area which allows the case hardening diffusion technique to penetrate much deeper into the ring fracture zone than in the other areas thereof. In this manner the reduced cross-section area of the outer ring provides a more brittle area with less of the more ductile interior steel which is more difficult to fracture. Such fracturing is necessary with such plain spherical bearings in order to allow placement of the inner ring within the outer ring. The spherical plain bearing produced by this method can include a single fracture or double fracture.

Abstract: The present invention is directed to a split bearing assembly and the method of manufacturing the same which substantially reduces material yielding and deformation during fracture. The bearing assembly includes a saddle-like main body with first and second legs and a removable saddle-like bearing cap with first and second legs. The ends of the cap are secured in end-to-end engagement with mating ends of the first and second legs of the body to define a journal receiving opening. The mating ends are defined by a portion of rough uneven mating surfaces formed by fracturing the cap from the body and a slot or saw-cut portion which operates to reduce the cross-sectional area of the first portion. The reduction in cross section of the mating ends, through the use of the saw-cut, operates to minimize the magnitude of the force which is required to initiate the fracture of the bearing cap from the body of the bearing assembly thereby limiting the deformation of the material in the fracture area.

Abstract: A assembly of mated molded parts and a method for making same are disclosed in which the assembly has first and second parts with precisely mating surfaces. The first part is formed by molding, casting, or the like such that the mating surface of the first part is formed with at least one protrusion. The second part is formed in place against the first part such precisely mating surfaces are formed with the second part enveloping the protrusion. The two parts thus formed are forced apart from each other. The protrusion may be formed with a head which interlocks with the second part. When the parts are separated, the head breaks from the protrusion. In a particular embodiment, a bearing cap is disclosed having a central opening for the passage of a shaft.

According to the method, a preform is made from a material having a carbon content of at least 0.5 percent by weight; the preform is separated by fracture separation at a separation location of the preform thereby producing the bearing cap and a remainder; skin layer hardening is performed on the running face thereby producing a skin hardened layer such that the running face acquires a Rockwell hardness of 55 according to the Rockwell cone method.

Abstract: A cross roller bearing is disclosed that achieves a long service life by reducing the effects of split surfaces formed in an outer ring in the direction that crosses a V-shaped groove of said outer ring. In addition, a cross roller bearing is disclosed that allows said effects to be reduced at low cost.The above-mentioned advantages are obtained by forming a recess in the outer surface of said outer ring corresponding to said split surfaces to reduce the preliminary pressure applied to rollers at that portion.In addition, the above-mentioned advantages are achieved at low cost by the filling of a filling member and the setting of the angle at which said split surfaces cross said V-shaped groove.

Abstract: A seal assembly capable of sealing a rotatable shaft protruding from a fluid-containing chamber in an internal combustion engines and the like. The seal characteristics of the seal assembly are largely attributed to surface interface between the seal cap and the main body of the seal assembly. More particularly, the seal cap includes a pair of legs each having fractured ends which are in end-to-end engagement with corresponding legs of the main body also having fractured ends. By mating corresponding fractured ends of respective legs of the seal cap and the main body, an improved seal is provided. A method by which such an improved seal assembly can be manufactured is also disclosed.
