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.
