Axial thrust bearing with radial movement

[alansimpson]

I am doing tests with spinning objects and I need an axial thrust bearing that allows some radial movement 2-3 mm.
Axial loading 10 Kg, 20 Lbs. Speed 200-500 RPM

At the moment I use a steel or ceramic ball 2-3 mm fixed to the to end of spindle. The spindle spins with ball coming into point contact with hardened polished steel surface of micrometer anvil 1/4 " dia. This is a bit of made up arrangement but it works quite well. I would prefer something off the shelf. Also I have no idea of how much wear is going on and what would be the best combination of bearing materials or ball radius

Jewel bearings are too small and "cup and cone" arrangements wouldn't allow radial movement. Axial thrust ball or roller races would result in roller noise.

I need radial movement as spindle finds it's own center.

I need low friction, low noise.

Environment is normal room conditions reasonable clean. Lubricants can be used.

Any input would be welcome.

Thanks
