A connection element providing a first ring and a second ring, the two rings rotating relative to one another about a central axis, the first ring having a contact portion with a contact surface interacting with the second ring for the relative rotation, and a fastening portion configured to be rigidly secured to a support. The contact portion is made of a first material and the fastening portion is made of a second material, different to the first material, the first material having a hardness strictly greater than that of the second material, and the second material having a structural fatigue strength strictly greater than that of the first material.

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.

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 bearing assembly includes a bearing cage and a supplementary ring. The bearing cage includes an annular body and a plurality of bearing elements disposed about the annular body. The supplementary ring includes an annular collar and a plurality of retention elements. The annular collar is disposed concentrically about the bearing cage. The plurality of retention elements is connected to and extends axially from the first annular collar. Each retention element is aligned between adjacent bearing elements. The plurality of retention elements is disposed to retain the plurality of bearing elements in the annular body of the bearing cage.

A spherical roller bearing providing an inner ring, an outer ring, rollers for rolling on raceways arranged on the rings, and a cage for holding the rollers spaced apart from each other. The cage having an annular core and a plurality of bars delimitating a plurality of pockets for the rollers, the annular core including two side faces from which the bars protrude axially outwardly, the inner and outer rings being rotatable with respect to each other around a bearing axis. The annular core further provides a plurality of spacing elements that protrude from the side faces of the annular core designed to come into contact with side faces of the rollers in order to prevent the rollers from moving axially towards the center of the bearing.

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 roller retainer cage for a roller thrust bearing, including a first cage half with an annular portion, a first flange extending axially from an inner peripheral edge of the annular portion and a second flange extending axially from an outer peripheral edge of the annular portion, a second cage half including an annular portion, a first flange extending axially from an inner peripheral edge of the annular portion and a second flange extending axially from an outer peripheral edge of the annular portion, wherein the first flange of the first cage half is disposed radially-outwardly of the first flange of the second cage half, the second flange of the first cage half is disposed radially-inwardly of the second flange of the second cage half, and the first cage half is comprised of a through-hardened metal.

A spherical roller bearing providing an inner ring, an outer ring, rollers for rolling on raceways arranged on the rings, and a cage for holding the rollers spaced apart from each other. The cage having an annular core and a plurality of bars delimitating a plurality of pockets for the rollers, the annular core including two side faces from which the bars protrude axially outwardly, the inner and outer rings being rotatable with respect to each other around a bearing axis. The annular core further provides a plurality of spacing elements that protrude from the side faces of the annular core designed to come into contact with side faces of the rollers in order to prevent the rollers from moving axially towards the center of the bearing.
