Bearing cage for a rolling-element bearing

A pair of components comprising:

• a first cage half and a second cage half configured to be ultrasonically welded to the first cage half to form a bearing cage for a rolling-element bearing,
• the first cage half and the second cage half each comprising an annular base body, a plurality of pins extending axially from the annular base body, and a plurality of pin receptacles complementary to the plurality of pins,
• wherein the plurality of pins of the first cage half are configured to extend into the plurality of pin receptacles of the second cage half and the plurality of pins of the second cage half are configured to extend into the plurality of pin receptacles of the first cage half to form bearing cage bridges and pockets configured to receive a rolling element,
• wherein the pins of the first cage half and/or the pins of the second cage half and/or the pin receptacles of the first cage half and/or the pin receptacle of the second cage half include a body of sacrificial material configured to be ultrasonically melted to connect the first cage half to the second cage half to form the bearing cage,
• wherein the plurality of pins of the first cage half each include an axial end wall,
• wherein the plurality of pin receptacles of the second cage half each include an axial end wall, and
• wherein the bodies of sacrificial material are located axially between the axial end walls of the pins of the first cage half and the axial end walls of the pin receptacles of the second cage half when the plurality of pins of the first cage half are located in the plurality of pin receptacles of the second cage half.
