Reference to M ø and M1 ø
These are long holes (elongated holes) e.g. 26/30 means;
Bore Ø 26 mm, designed as long hole with a length of 30 mm.
Why?: When mounting the pulleys, the position and feeding angle of the rope in the pulley respectively, can be fine-adjusted by a slight movement of the pulley within the long hole.
