Is it necessary to leave an axial gap between the impeller positioning split ring and the impeller, and what should be the appropriate amount of this gap?

May I ask which two parts are the positioning collar and the split ring? Please send over the complete drawing with icons. Also, it seems that no axial clearance is necessary; this component is originally used to fix the position of the impeller and ensure its correct location. If an axial clearance is left, could the impeller move or fail to be held firmly in place?
I checked the newly arrived split ring and found a gap of 0.10
0.1 is considered a tolerance value; it can be set according to one’s own requirements for precision in processing. In principle, the smaller this value, the better
It depends on the manufacturer’s design philosophy. Some have gaps, while others have no gaps
