The invention relates to a rolling element bearing cage formed of one or more segments, each segment comprising: a supporting frame having a plurality of spaced apart openings each for accommodating a rolling element; and a reinforcing frame, inserted within the supporting frame, having a corresponding plurality of openings each for aligning with the openings of the supporting frame.

A split bearing cage for a rolling-element bearing assembly includes a first bearing cage segment and a second bearing cage segment each having two side ring sections axially spaced apart by a plurality of bridges. Adjacent pairs of the bridges define rolling-element receiving pockets for receiving rolling elements of the rolling-element bearing assembly and for holding the rolling elements spaced apart from each other and for guiding the rolling elements. The first bearing cage segment is connected to the second bearing cage segment via a swivel joint that may be formed of a bolt element on a first end of the first bearing cage segment and an at least partial eyelet on the first end of the second bearing cage segment.

The invention relates to a roller bearing cage comprising: a first annular ring; a second annular ring; at least one retainer portion attaching the first annular ring to the second annular ring to form the first and second annular rings in a cylinder-type structure; and a plurality of resilient tangs on each of the first and second annular rings, each tang protruding from the circumference of the respective annular ring at an angle with respect to the plane of the respective annular ring and toward the other annular ring.

A cage of a cage and rollers includes engaging projecting portions that are provided on outer circumferential surfaces of rim portions, the engaging projecting portions being configured to be elastically deformed when the cage is inserted into a support hole of a rocker arm to thereby allow the cage to be contracted in diameter and to be elastically restored to be brought into engagement with the rocker arm after the cage is inserted in the support hole, to thereby position the cage properly in relation to an axial direction relative to the rocker arm. The cage and rollers can be assembled to the rocker arm while being positioned properly in relation to the axial direction so that the cage and rollers and the rocker arm can be formed into a rocker arm unit, and the cage and rollers can easily be assembled to the rocker arm.

The invention relates to a method of forming a roller bearing cage comprising: forming a planar strip of material, having a length corresponding to a circumferential dimension of a roller bearing cage; forming openings in the planar strip, corresponding to positions at which rollers are to be located; forming a plurality of tangs, alongside and part of each side of the length of the planar strip, each tang having a first tang edge of a first length adjoining the strip and a second edge of a second length opposite the first tang edge; and bending each side of the length of the strip such that the plurality of tangs is positioned at an angle with respect to the planar strip, wherein the fold is through an angle of greater than 90 and less than or equal to 180 relative to the plane of the planar strip.

The invention relates to a rolling element bearing cage formed of one or more segments, each segment comprising: a supporting frame having a plurality of spaced apart openings each for accommodating a rolling element; and a reinforcing frame, inserted within the supporting frame, having a corresponding plurality of openings each for aligning with the openings of the supporting frame.

Disclosed is a rotatable module, which includes a lower ring and an upper ring, wherein a top surface of the lower ring forms a concentrically-arranged annular groove, and the upper ring is embedded in the annular groove to form a coaxial rotational fit with the lower ring; the lower ring includes a first half-ring and a second half-ring that are detachably spliced into a ring, and the upper ring includes a third half-ring and a fourth half-ring that are detachably spliced into a ring. The invention is easy to collect and store, takes up less space, and has better portability.

A cage for a crankshaft bearing or a connecting-rod bearing of an internal combustion engine or for a compressor has a plurality of receiving pockets for guiding bearing rolling elements and has an axial width. The cage includes at least first and second cage segments, each cage segment having a segment axial width equal to the axial width of the cage and having a first end circumferentially spaced from a second end, the first cage segment first end being connected to the second cage segment second end by an interference fit and the first cage segment second end being connected to the second cage segment first end by an interference fit.

The disclosure provides an improved split bearing cartridge assembly and split bearing housed bearing assembly. The split bearing cartridge assembly comprises a split inner race fixedly securable to a shaft, a plurality of rolling elements retained within a cage, a split outer race rotatably securable to the rolling elements, a split bearing container for substantially encapsulating the split inner race, split outer race, rolling elements and cage, and first and second sealing means for sealing between the split inner race and first and second openings, respectively, of the bearing container. The split bearing cartridge assembly may be combined with a split housing resulting in an improved split housed bearing assembly.

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.
