Default Do urethane caster wheels deform over time under load

This question is of great interest to me. If, say, I has a 1500 lb
rated caster with a urethane wheel, would it deform under 800 lb
load, enough to make it troublesome to move. Thanks

What color are they? The softer Urethane will deform but the harder ones
will not. In die work, Urethane is color coded to hardness but I'm not sure
if is an adhered to standard and may even vary per mfgr.


At the risk of causing a serious consternation, I want to confess that
I am going to make a base for this mill on casters. I will need to
move it about quite a bit. We are likely doing a house addition this
year and the mill will move into the new shop. I can always put 2x4s
under the base for stable placement.

Anyhow, I have these Colson 1500 lbs casters with dark red urethane
wheels, and I want to know if they would become unusable if I let the
mill sit on them for a week or two.

I made a base for my mill which wieghs aroud 700KG I used 4 x 200KG
casters with the red urethane ,I made and attached screw down jacks to
the four coners of the base so I could jack the weight off the wheels
and level the machine .It also makes it alot more stable when using it.I
was worried about the urethane flattening and the wheels moving while
using it .
When I need to move it I just screw the jacks up and lower it onto the
wheels, reposition and raise it on the jacks an level .
