I sucked grease - by manually pulling the plunger with a dab of grease
on the bottom air input - into my cylinders and they move more
consistently and don't leak pressure. I used ceramic grease of the
type you get for RC car gearboxes. They aren't much easier to move,
but they do move more smoothly and I've not had the problem with
pressure leakage. I can't say I put much lateral stress on them
though.
The same grease on a large turntable worked as well - perhaps harder
to turn but no sticking at all, making precise movements easier.
