[FTC]: FTC Ball Bearings

[Matthew Blake]

Are we allowed to use ball bearings in FTC?

Thanks!

No. the only exception would be the really tiny ones from the tetrix pivot bearing kit (http://www.legoeducation.us/eng/product/pivot_bearing/1619). It looks big in the picture, but it is only just big enough to fit a #2 or 3 machine screw through the center bore.

EDIT: Actually, with any type of threaded rod under 3/8" being legal this year, one might be able to make this work for some light-duty applications other than the one it was specifically included in the kit for.

Only if you can make them from approved materials stated in <R5C> of the rules.

Roller bearings should be somewhat easy but ball bearings, although doable, would need specialized equipment.

Does it have to be a ball bearing or just low friction?
