    I am concerned that if you order, and they just send you what they have , what happens if you need a spare/replacement ? will it fit ? or not ?

    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.

    At ebay there are for the same money or just a bit more, shipped from UK warehouse. Why don't you check?

    too late :) ... paid :/

    any way .. I'd like to try out the "ali" process and see if it works out ok .. the rails and bearings seem very cheap ! :)

    one of my routers spun a bearing today (I have a couple of backups).. so it made the spindle issue more urgent :)

    so ... to bring this thread back ...

    I've bought a 2.2 wc spindle off of Ali

    Linear rails/bearings next ..

    anything to avoid ? or just go by price ?

    Thanks

    Avoid sellers without rating.

    Stick to trusted sellers. /Chai or Fred/

    Avoid TBR or SBR rails, buy square supported. Chinese, TBI, Hiwin,THK, Rexroth, / ordered by price/. TBI or Hiwin are the usual choice.

    The 15 size are strong enough but the usual choice is 20.
