I am looking for a replacement bearing for an old lathe. The lathe spindle assemble features a collet-like bronze bearing with a nut for tightening the inner diameter.

enter image description here

Unfortunately, I cannot find this style bearing at the required size. Is it possible to use a bearing adapter sleeve inside a plain bronze bearing?

If not, are there any suitable alternatives that would allow me to reduce shaft runout?

I would check McMaster and Misumi to see if a a stock bearing or flange bearing would fit. If not get one sizer smaller and (hand) ream to inside diameter needed.
