My guess is that they use materials with impregnated lubricants, or materials which naturally have high lubricity. Most likely, they stay away from grease or oil lubricants, as these can easily attract debris while also not be reliable after being in the vacuum of space for a while.
But that is just a guess. I would be very interested in hearing what is actually used.
