Linear bearing upgrade options?

[Boyan Silyavski]

The problem could be also the shaft. There are some super nice plain Frelon bearing blocks from PBC Linear and similar, but if your shaft is not ok the result will be short life.
Check their tech info. But as i see it you need brand bearing, plain or ball, if you expect a real upgrade

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
