c sized bearing diameter

what is a C sized bearing diameter in mm? i am designing my own yoyo and i need to know the scale of the bearing. if it is good, i will learn how to use a lathe and make it myself!

Surely you know the power of Google? I typed in “size c yoyo bearing” and got the specs right away. .250 x.500x.187 which is in inches. If you convert that into milimeters you get— 6.35mm x 12.7mm x 4.7498mm.

Good luck with your yoyo that your building/designing. Let us know how it goes.


i have done that. that is the inside, outside, width. should i assume that it means outside diameter?

Ye, cUrlYo.
