Abstract

A bearing cage for large radial or axial roller bearings, which has two axially opposed, circular ring-shaped side washers held at a distance to each other by connecting elements, and roll-shaped rolling elements disposed between the side washers which have bolt-like elements on the faces thereof. A side washer on at least one side of the rolling element has radial recesses into which the bolt-like elements protrude. At least one securing element suitable for holding the bolt-like elements in the area of the radial recesses in the assembled state is provided. Shaped elements that can each be introduced at least partially into the radial recesses of the side washer are provided as the securing element. This construction achieves easy assembly and disassembly of the housing, allowing high flexibility in repairing a roller bearing so equipped.
