A method for producing an annular-shaped cage for a rolling bearing assembly. The method comprises steps of: (a) providing a workpiece contained in a plane having a first side and a second side; (b) forming an annular-shaped cage from the workpiece, the annular-shaped cage having a U-shaped cross section such that portions of the first side of the workpiece face each other; and (c) forming a plurality of windows in the workpiece for receiving and positioning a set of rolling elements.

A thrust bearing includes: a retainer that is provided with a plurality of pockets; a plurality of rollers that are arranged so as to freely rotate inside the plurality of pockets; and at least one first race that has an annular-shaped first race section in which the plurality of rollers move. The first race is provided with a hook curl section that is formed by bending the first race section from an outer-diameter-side periphery thereof toward the inner-diameter side obliquely in the radial direction, and an outer peripheral surface of the retainer has a conical surface that is formed so as to be substantially parallel to an inner peripheral surface of the hook curl section. The inner peripheral surface of the hook curl section holds the retainer without separating therefrom by contacting the outer peripheral surface of the retainer in a sliding manner.

A bearing cage for retaining rolling elements of a rolling element bearing, the bearing cage having at least one first ring structure to which at least one first cage bar is connected. The bearing cage also comprises a second ring structure to which at least one second cage bar is connected, whereby the at least one second ring structure is arranged to be located radially inwards of the at least one first ring structure.

A crankshaft or connecting-rod bearing assembly of an internal combustion engine includes a bearing journal configured to function as a bearing inner ring, and a bearing outer ring surrounds the bearing journal. At least one row of rolling elements is disposed between the bearing journal and the bearing outer ring, the rolling elements are held by a cage, and the cage includes at least two cage segments, each of which extends around a circumferential section of the bearing journal. Furthermore, the at least two cage segments are connected to each other in a materially-bonded manner at at least one joint lying in the circumferential direction.

A snap-fit box cage including a first and second ring is provided. The first ring includes a first radially outer flange, a first radially inner flange, and a first radial portion extending therebetween. At least one of the first radially inner flange or the first radially outer flange includes at least one retention projection. The second ring includes a second radially outer flange, a second radially inner flange, and a second radial portion extending therebetween. At least one of the second radially inner flange or the second radially outer flange includes at least one retention recess that is complementary to the retention projection. The first and second rings are matingly secured to one another by the at least one retention projection and the at least one retention recess resiliently engaging with each other, and the rings captively secure rollers installed in pockets formed on the rings.
