[FTC]: FTC Ball Bearings

Are we allowed to use ball bearings in FTC?

Thanks!

Re: [FTC]: FTC Ball Bearings

No. the only exception would be the really tiny ones from the tetrix pivot bearing kit. 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.

Re: [FTC]: FTC Ball Bearings

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?
