Ballscrew & Linear Rail Kit - Any Good

[Clive S]

I am not saying that there are no lemons, but that most are OK for hobby use and there is no reason to rush or assume that everything is bad. Of course if one is replacing the bearings one might as well do it right and get the proper ones. But you can't say that just because some people have issues all are having them. In my experience there was a huge quality improvement in these things the last few years, can't compare with how things were like ten years ago. Yes, they do use these simple bearings, but unless it is specified otherwise, there is nothing wrong with that, they didn't fool you. It's not for industrial use, if it was then I'd be more critical about them.

That's the point they were not specified that's why I asked him to check. They are being sold in a kit with rails so should be AC type.

As the op is a beginner he would not know the difference between the bearings so why do you muddy the waters.
