Accuracy: JIS B 1558, JIS B 1559
Bearing Inner Diameter Tolerance: H7 (Clearance Fit)
Operating Temperature: -10 ~ +80°C
[ ! ]*2-M (Set Screw) angles for Set Screw Fixed Type are 120°.
[ ! ]Eccentric Ring Fixed Type has one set screw and one through hole, with an angle of 90°.
[ ! ]Eccentric rings are used to secure shafts.
[ ! ]Ball bearing moves slightly due to self-aligning function.
[ ! ]To maintain transition fit, the fit between the main body and the bearing is designed slightly tight (Except Cast Iron Type). If the bearing is inclined when delivered, insert the shaft into the bearing to adjust the inclination.

■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.
