An annular-shaped cage assembly for a rolling bearing assembly, the annular-shaped cage assembly comprising:
- an annular-shaped cage having a U-shaped cross-section and a plurality of windows for receiving and positioning a set of rolling elements,
- the plurality of windows is arranged spaced apart along a circumferential direction of the annular-shaped cage,
- a locking ring engageable with an open side of the annular-shaped cage for securing the set of rolling elements,
- the locking ring is provided with an integrated seal for sealing the locking ring to the annular-shaped cage.
A method for producing an annular-shaped cage for a rolling bearing assembly, the method comprising steps of:
- providing a workpiece contained in a plane having a first side and a second side wherein the workpiece is provided in a form of a longitudinal workpiece, the longitudinal workpiece having two opposing longitudinal edges, a first transverse edge and a second transverse edge;
- 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
- forming a plurality of windows in the workpiece for receiving and positioning a set of rolling elements.
A method for producing an annular-shaped cage for a rolling bearing assembly, the method comprising steps of:
- providing a workpiece contained in a plane having a first side and a second side;
- forming an annular-shaped cage from the workpiece by bending the workpiece about a transverse axis, the annular-shaped cage having a U-shaped cross section such that portions of the first side of the workpiece face each other;
- and
- forming a plurality of windows in the workpiece for receiving and positioning a set of rolling elements.
