Dont worry about that.

I am talking about ballnut housings and brackets. You will never need to replace that.

About the spindle, the only thing you could possibly replace there, are the 4 bearings, they sell them cheap at aliexpress. However possibly one day would be cheaper to buy a new one, depends how you value your time. 4 bearings cost ~20eur . I messed once with my spindle, but only because was desperate to finish an order, and because i want a bigger one, otherwise i would have simply bought a new one. Still works like a beast though.

About the ballscrews and nuts, i doubt you will ever need to replace any of them, but they are standard.

However things like HDT belts, HDT pulleys and so, i always buy extra, cause if i mess one, then have to pay extra shipping, they are cheap.
