On thrust bearing naturally performs radial bearing

Sorry if it's really mechanical, not electrical, engineering at all

Isn't a thrust bearing, as a matter of course, performing a radial bearing work ?

All 'Thrust Bearing' means, is a bearing optimised for or intended for axial loads, usually unidirectional.  It may or may not have a lesser capability for radial loads, depending on its design and construction.  e.g. a ball thrust bearing with grooved races can act as a (poor) angular contact bearing and resist radial loads up to a small fraction of the applied axial load, but a roller thrust bearing with flat races will rapidly be damaged by even small radial loads.

On radial load thrust ball bearing performs no better than normal ball bearing for axial loads.

show the picture of you motor and gearing/linkage involved, then we can talk same dictionary. some bearing only radial, some only thrust/axial, but some at an angle, can do both.

The simple answer is no, a thrust bearing is not by default a radial bearing.  If the thrust bearing is made  with balls instead of rollers, then it may take a radial load depending on how it is made.  However, the nature of a thrust bearing means that it may not take any radial load at all (see attached image).

In my experience thickness of a thrust bearing is important.  That is, you want them as thin as practical for the load.

There's a reason that for ecample lathe live centers are made as they are.
Here you go, I think it answers your question:

So just been browsing over many threads under this category of forum, now Imho. EEVBlog electronics community forum is deserved to become EEVBlog electronics, mechanical and industrial engineering community forum as some of its categories are really not merely electronics stuffs, to which I'll be moving up from many Physics/mechanical forums I've been in, and not as active and useful as this

Thanks a lot to all for the truth given which'd help solve the problem !
