1. Roller bearing with various diameters and with a segmented cage (1) for guiding the roller bodies (2), comprising in each casean inner ring (3), on whicha plurality of roller bodies (2) can be rolled, which can also be rolled onan outer ring (4), which is concentric with the inner ring (3),anda cage (1), which comprisesa plurality of webs (11),which are distributed in a uniform manner about the periphery andare aligned so as to be parallel to the surface of a roller body (2) (1), anda plurality of lateral plates (12) for connecting the webs (11) andwebs (11) and lateral plates (12) are firmly connected to one another to form cage segments (14), which in each case form a pocket for guiding a roller body (2) andAll cage segments (14) are connected to one another rigidly in pairs only via their relatively large cross-sectional area to form an inherently closed cage (1),characterised in thata cage segment (14) consists of at least one web (11) and two lateral plates (12) andfor a small variation of the diameterthe webs (11) and the lateral plates (12) of a cage segment (14) have a limited elasticity, which permits identical cage segments (14) to be rigidly connected in various numbers to form an inherently closed annular cage (1) andfor a relatively large variation of the diameterIntermediate wedges (15) can be inserted between the webs of adjacent cage segments (14), the connecting surfaces (151) of which to the webs (11) are formed so as to be complementary to the outer sides thereof, and variants of the intermediate wedges (15) with different angles between their two connecting surfaces (151) can be assembled with cage segments (14), which are in each case identical, to form cages (1) with different diameters.
