Ahh, It's been a little hard to tell what you wanted. Maybe a piece of rubber tubbing as part of the coupling to the pot? (or heat shrink as previously suggested)
Are you making one of these, tens, hundreds? (At the tens level it's silly to worry about a few bucks.)

Well ... there used to be pots designed for use in servo assemblies (as position feedback) and similar things. 360 degrees rotation, the ability to set taps wherever you want them on the resistance element, and the shaft mounted in ball bearings (1/4" shaft typically). One of these would certainly be strong enough, if mounted structurally. It is not designed for printed circuit mounting, but rather for mounting in a precise hole, held in by clamps, and allowed to rotate to set the zero point before the clamps were tightened. Given the bearings, and the very low contact force wiper, it has almost no drag.
One of these would certainly handle the loads, but while I never bought one of these new (just from eBay or at hamfests) I'm willing to bet that they would be *very* expensive compared to what you need.
Good Luck, DoN.
Those are similar to the Chromakey pot used in high end video consoles. They had four 90° taps and cost ^ $1000 in the '70s.
