Although the bearing height for balancing is horizontal, the center of the hub mounting part collar does not fit, even if the wheel is attached, it becomes oblique. The boss of the screw part is obliquely welded. Also, although I do not know at the time of transportation, the level instrument is included with the screw bag and it was broken and could not be installed. Although somehow it could be modified to the level where it can be shaken, it is not recommended much.
At the time of assembly, I was dissatisfied that there was not one weld of the nut and the welding of the nut was misaligned and processing was necessary. Since I needed an option, I think that it is better to write that point in the explanation.
