Linear bearing upgrade options?

[Joe]

I counted the balls and there was one missing on one of the races but that was the smooth one!! Who would have thought that!

I think that there is to many things I would like to improve and by just upgrading the bearings that probably isn't going to do it and may well be a waste of an investment. I am probably going to upgrade to a hiwin RG type rail in the future and larger better quality ballscrews but that investment will have to wait a bit longer

I have checked the shafts and they are all prefect as far as I can see and measure but there are only limited screws holding the rail to the aluminum profile which is a sorce of flex as well as the bearing

I took some pictures so you can see the machine anyway but thanks for your help guys !

Just upgrading the rails would give you an enormous improvement. Looking at the pics the screws seem fine are they 1610 x and y and 1605 for Z ..Clive
