This is not an ideal setup for a normal machine, even for a heavy duty one. Its better to use the normal angular contact bearings, which are more than enough for the job by any

Now i know more having run my machine a couple of years daily and having made the kit for a couple of people.


I already sait it there #122 , and couple of posts after that.

Not only there is absolutely no gain but there will be loss, using these bearings.


Now if you are constructing a lathe head, then go with them
