Yah, I've seen those. I could make those work if the wheels
were rubber. It has to travel across textured ceramic tile
so steel is out.

I've looked for soft casters for tile too. Only ones I found are the
hooded rubber ones and a two wheel furniture caster (stem or plate) that
has relatively hard urethane as wheels rather than plastic. Haven't
tried the latter. Home Depot usually has both kinds.

The hooded rubber ones work well but are held together simply by the
stem being punched over the plate; because of the offset nature, there
is a lot of pressure/torque on that connection and if the load is heavy
(normal man in a chair with four casters) it will fail at which time you
have ball bearings all over anywhere.
