Is a r188kk bearing really needed, or will a r188zz also do? I'm not sure, but they seem to have the same measurements, only differing in the material.
And what is the function of the O-rings? (edited)

@MIAL_158961 hey, I think r188zz should work also. they are just sealed. but I think it is important that the bearing should be yoyo bearings. so that the outer wall is curved inside to hold the cord. seams like they are called ur188 bearings.
@andimoto UR188 seams to be ceramic bearing. but i mean R188 for yoyos
@AstroJohn Thanks!! This is a nice golden color!! Have fun!
