Abstract

A roller bearing (e.g., a cross taper roller bearing) includes an outer ring, an inner ring and rolling elements (e.g., taper rollers) located between the inner and outer rings. The rolling elements are kept at a distance by a cage formed from a number of individual cage segments. Each cage segment has two opposing guide sections for one of the rolling elements to at least partially encompass the rolling element on both sides. In addition, for the rolling elements bordering the one rolling element, the cage segment has guide sections which, in interaction with a corresponding guide section of an adjacent cage segment, at least partially encompass the bordering rolling elements.
