Re: Ball bearing life why so short?

 

Maybe the axial loading when machining on a lathe?

Of course, all the drill presses I've been inside of have ball bearings and most of their load is axial in spite of that.? But maybe the axial forces involved in using a drill press aren't as large as those when using a lathe.

Or it could just be cheap bearings or even cheap lubricant.

I have used the 6206 bearing in motors and doors. The life for a seal 6206 ball bearing is 20,000 to 60,000 hours.
In a mini lathe a lot shorter.?
Why is it so short?
