Abstract
A two-part bearing cage for a rolling-element bearing includes first and second identical cage halves each including an annular base body, a plurality of pins extending axially from the annular base body, and a plurality of pin receptacles, each of the plurality of pin receptacles having a shape complementary to a shape of a pin. Each of the pins on one cage half engages into one of the receptacles of the other cage half to form bearing cage bridges and pockets between the bridges, and each of the receptacles includes a radially outwardly disposed, axially extending ring wall section that radially outwardly supports the pin received in that receptacle.
