A bearing cage assembly including two different cage halves formed from different materials is disclosed. The first cage half includes a first rim and a first plurality of arms extending from the first rim. The second cage half includes a second rim and a second plurality of arms extending from the second rim. The first cage half and the second cage half are fastened to each other via engagement between a plurality of first retainers of the first cage half with the plurality of second retainers of the second cage half.

A snap-fit ball bearing cage, including: a first ring-half supported for rotation around an axis of rotation and including a plurality of first curved surfaces; a second ring-half including a plurality of second curved surfaces and a plurality of first protrusions non-rotatably connecting the second ring-half to the first ring-half, each first protrusion forming a portion of a radially outer perimeter of the second ring-half, or each first protrusion forming a portion of a radially inner perimeter of the second ring-half; and a plurality of balls. The plurality of first curved surfaces and the plurality of second curved surfaces define a plurality of openings; the plurality of balls is disposed in the plurality of openings. Each first curved surface, included in the plurality of first curved surfaces, is a mirror image of a second curved surface included in the plurality of second curved surfaces.

A high-speed ball bearing utilizes a two-piece cage. Each of the two cage halves have a set of posts and a set of holes located circumferentially between the half pockets. The posts are long enough that they stick out from the corresponding holes after the cage halves are mated together. Heat is applied to the ends of the posts, causing them to form vulcanized bonds with the surrounding material of the opposite cage half. These bonds reliably hold the cage halves together even at high rotational speeds.

A bearing cage assembly is disclosed that includes two sub-assemblies. Both cage sub-assemblies include a shell half formed from plastic, and defining a plurality of rolling element pockets and openings. Each sub-assembly also includes a frame half formed from metal, and including a rim and a plurality of crossbars. The shell halves are overmolded with the frame halves. The first cage sub-assembly and the second cage sub-assembly are connected to each other via insertion of the crossbars into the openings of the other sub-assembly, such that free ends of the crossbars engage the other rim.

A bearing cage assembly is disclosed herein that includes a first cage half formed as a plastic cage and a second cage half formed as a metal shell. The first cage half includes a first base rim and a first plurality of arms extending axially from the first base rim. The second cage half includes a second base rim and a second plurality of arms extending axially from the second base rim. The second plurality of arms are each formed by a first flange and a second flange. The first flange and the second flange are spaced apart from each other in a radial direction to define a receptacle dimensioned to receive a respective one of the first plurality of arms. Free ends of the first flange and the second flange are crimped over to retain the first cage half with the second cage half.

A bearing cage includes a first annular body having a plurality of circumferentially arranged fingers that extending axially therefrom. Each of the fingers have a tab with a first arcuate engagement surface. A second annular body has a plurality of circumferentially arranged finger-receiving holes extending axially and configured to receive the fingers. Each of the holes have an associated second arcuate engagement surface configured to engage with the first arcuate engagement surface when the fingers are received in the holes to secure the first and second bodies together to form the bearing cage.

A two-part ball bearing cage includes two, in particular at least substantially identical, cage parts forming an even-numbered plurality of ball pockets for receiving a corresponding number of balls having a predeterminable ball diameter. Each cage part has an annular body on which substantially evenly distributed webs are disposed in the circumferential direction to form the ball pockets. A distance in the circumferential direction between two webs that are adjacent in the circumferential direction approximately corresponds to the sum of twice the ball diameter and a width of the web in the circumferential direction. A ball bearing having the ball bearing cage and a method for assembly of the ball bearing are also provided.
