H8 tolerance of the inner bore refers to the machining tolerance before slotting.
After slotting, only h7 or h6 tolerance fit with the shaft is guaranteed, and concentricity is not guaranteed.

The appearance of economical series products may have slight dents or scratches.

The depth of the slots on both sides of the inner bore may vary depending on the outer diameter and bore size.
