SHAFT ISSUES
-
I have observed that there are long scratches on shafts, probably developed as a result of usage.. is it normal with all machines, I think my bearings can't last long on these shafts..

@vivek.khanna No this is not typical, perhaps you have grit in the bearings that is scratching the shafts or the bearings are not working correctly.
