Hi Kerst,
The leadscrew bases are held in with sealed ball bearing units, so that end is good. The screws themselves are polished steel with bronze followers, so they are designed to be able to run dry in the robotics world, but given the loads on the model I figured I would give them a thin coat of CopGraf for good measure. By pulling the crosspin on the tips of the cylinders, the piston can be unscrewed from the leadscrew and removed for access.
