The arms use sealed spherical bearings with self-lubricating Teflon liners in place of rubber bushings.

On top of that, every arm wears a military-grade Cerakote ceramic hard coat, the same kind of finish used on firearms and aerospace parts, to resist corrosion and stone chips. Daily reliability was a design target, not an afterthought.
