Do any castors survive long-term stationary load, for occasionally needed mobility?

[Carlos]

Oh, and yes, I know my shop needs a cleaning VERY MUCH, but I've been doing garden projects and motorcycling while the weather is nice and neglecting the wood hobbies.

Am I missing something? I don't see how that bottom picture of Carlos possibly works.
Clearly its supporting the device as the leveling foot is up in the air.
But it can't roll. its trapped; and it can't swivel, the bearing is not in the horizontal plane. No roll, no swivel, what's it doing?

[Carlos]

Hah, I thought you were crazy then looked back at the pic. I didn't even notice that the wheel had been kicked under. Here's how it actually looks when it hasn't been kicked.

And the lock nut on the stationary foot is supposed to be jammed against the bracket to keep it from changing height once leveled, not uselessly run all the way down to the foot.

You just solved the problem I've been having with my router table for years. I didn't move it often enough to really think about it until the feet started dragging halfway through the move.

I've been tweaking the level to get it just right. It's amazing how much the floor level varies in a couple inches. You can also see that my dot is missing, because I'm rethinking the landing spot based on finding the flattest exact locations. I had those non-slip Fastcap dots on the floor to mark the location and to keep it from moving at all.

Also, I think my design is pretty cool. It keeps all my power drivers/drills at hand, all of them chucked with all the bits needed for a job. Bit holder right there. The top has a coffee table type hinge mechanism so that there's convenient project parts holding right there. The coffee table hinge keeps it flat so there's still a surface, and it raises it well enough to use standing. I can roll the whole thing out to a project as needed.

That's a very good looking rolling bench, Carlos!

My bandsaw, 8" jointer and edge sander all ride on custom lifts with 2" Darnell-Rose casters. Expensive but worth it to me. I used 3 1/2" polyurethane casters from Grizzly under my DP cart, router station and tool cart.

I don’t think it is the load on the poly casters that make them break. I believe it is a factor of time where the ester base urethane, being hydroscopic, which means it absorbs water. During its life span the material pulls moisture from the surrounding air which breaks down the polymer chains. Eventually the plastic shrinks, cracks and falls apart.

I do not think that it is a bad idea to jack up a cart of work bench to take the load off of the poly tire. It can’t hurt and may extend its life.

I have seen used caster tires stored in my shop closet crack and fall off. They were possibly over 10 yrs old or older.
