Long bearing for 3/16" shaft

[esbdmb]

Hi, I'm looking for a long cylindrical bearing to press on 3/16" shaft, would need to be 2" long and as small OD as possible. Any thoughts?

Check out a needle bearing:

(download the needle catalog and look on page B-2-54)

I doubt there is anything 3/16" x 2". But why not put one on each end with a spacer?

Any information on the speed and loading of the bearing?

I'm thinking I don't know if this bearing is going to handle an axial load, a purely radial load, a moment, or some combination of all 3, and if it is operating at 850 degrees F and 140,000 rpm

A plain sleeve bearing is an option. It does not have to be one piece that is 2" long. Only a short section of the bearing where the rod enters the sleeve we carry any load.

Not an answer to your question but check out Air Bearings as in Westwind.
