Re: Ball bearing life why so short?

I would offer that "DEEP GROOVE" bearings do NOT have good axial load potential.
?
plus?
The fact that the bearing 6206 seems to be big and chunky in your hand and by human force standards, when the machine is applying load to the bearing in the axial direction, it may still be being overloaded by the massive mechanical advantage the lathe can generate.

plus
Cheap bearings.

Maybe switch to sealed 7206 Angular Contact bearings similar to --> ? , installed in opposing directions.

Good Luck with your continued research in this matter.

They use type of deep groove on live centers too.?

They are not designed for heavy axial loads - like heavy (for a mini-lathe) cuts.
