A roller bearing cage comprises first and second annular elements, each having at least three radially-extending bulges or indentations spaced around a circumferential direction of the annular elements. An axially-facing surface of each bulge or indentation serves as a guide surface for one axial end of a roller body. A plurality of bridge elements are bonded to and connect the first and second annular elements. Each bridge element is disposed between two adjacent bulges or indentations on a radial side of the annular elements that is opposite of the extension direction of the radially-extending bulges or indentations. The bridge elements are configured to support rolling surfaces of respective roller bodies such that a pocket for a roller body is defined between each two adjacent bridge elements and each two axially-opposing, radially-extending bulges or indentations.
