Slew bearings can take forces that a roller bearing and a thrust bearing can't deal with. Buying the balls in bulk and printing your own bearing is far more economical than getting a $160 slew bearing machined way beyond my needs.
I put this in Camera because I've seen the same bearing used in astronomy for star tracking. I'm experimenting with using it in my robot arm project.
