More Information
■How to Secure the Shaft
| Set Screw Fixed | •There are two set screws at the end face of the bearing inner ring (at 120°). The shaft is connected by tightening the set screws. |
| Eccentric Ring Fixed | •Dissociate the centers of the convex outer surface at the end of the bearing inner race (part a) and the concave inner surface of the eccentric ring (part b), connect the shaft and the inner ring by forming a wedge on the circumference (Refer to Fig. 1). •Also, there is a set screw and a hole each (at the angle of 90°) on the end face of eccentric ring, which helps to prevent loosening by using the set screw as well as tightening as described above. •The D hole is for inserting a small diameter rod when loosening the connection. |
