This model can be installed in the same mounting hole as that of the popular type Cam Follower. Since the mounting shaft of the stud and the stud head are eccentric by 0.25 mm to 1.0 mm, the position of this model can easily be adjusted simply by turning the stud. Thus, it is a compact, highly accurate eccentric cam follower with an integral structure. As a result, machining and installation man-hours are significantly reduced, due to easy positioning with the cam groove and precision machining of the mounting hole position being unnecessary.
