Anyone knows suppliers that can provide customised cleanroom compatible swivel wheels?

I am trying to design a product with swivel wheels that works in a cleanroom with the following requirements but have been unable to find a supplier so far due to the small wheel size needed.

- Resistant to aggressive detergents/corrosion

- Wheel diameter of 1/2"

-Non marking wheels

-Sealed bearings

-Anti static

Does anyone have experience interacting with suppliers who provide such swivel wheels? Or even suppliers that are able to provide some form of customisation for cleanroom wheels?
