Precautions for Use

In case of mounting on D-cut shaft, be careful about the position of the D-cut surface of the shaft. ⇒Mounting and Maintenance
There are sizes where the hex socket head bolt exceeds the hub outer diameter of the coupling and the rotating diameter is larger than the hub outer diameter. Please be careful of the interference of coupling.
