Abstract

A bearing cage for a rolling element bearing includes a plurality of individual bearing cage segments configured to respectively accommodate rolling elements in rolling element pockets formed by the bearing cage segments. Each bearing cage segment includes a first coupling device disposed on a first axial end thereof. A first lamellar support ring defines first and second ring halves that are connected to each other, are axially adjacent to each other are biased towards each other. The first ring half extends through the respective first coupling devices of the plurality of bearing cage segments and the second ring half is disposed on an axially-inner side or an axially-outer side of the first coupling devices such that the first coupling devices are clamped between the first and second ring halves.
