Abstract

The invention proposes a lever-type cam follower (1) which, for mounting a pin (7) for a cam roller, comprises bores (5, 6) in the region of its side walls (2, 3). The diameter of the bore (5) is larger than the diameter of the bore (6). Corresponding ends (8, 9) of the pin (7) are configured so that when mounted, the pin (7) is fixed in the bores (5, 6) by a press fit. Thus, the pin (7) can be inserted with its second end (8) at first through the larger bore (5) without causing damage to its raceway (8a) during assembly. At the same time, the press fit guarantees an excellent fixture of the pin (7) in the cam follower (1) with an all-round contact.
