High Temp Caster

[UchidaDS]

I am looking for caster, most likely to be stainless and will be used in high temperature, about 280-450C. It should handle at least 200lb per caster.
As I know most caster come with greased, or plain bearing. This specific caster should not have grease, no bronze filling.
Do you know where to get it?
Size of the caster is not the main concern.

Maybe add terms like 'clean room compatible' to your search phrase?

I did try that. But the temperature does not meet.

Almost certain to be a custom made thing. Possibly you could modify something off the shelf.

Look at General Magnaplate Hi-T-Lube or Magnamax-HT as a coating for a plain bearing.

Graphalloy sells cam followers that go pretty high, also sell bushings and bearings. Pretty nice folks, give them a call, they may have solved your problem before.

Oh yeah, clean room stuff typically uses plastics that may not last long at your temps, sorry.
