I am planning on making Articulating Arm Hollowing System similar to Captains Eddies Snake Hollower or the Monster Hollowing System. I have most of it planned out but I need some assistance in figuring out what bearing I should use in the joints. I have come up with the three options below, please let me know what you think?

Ben, if it were me I would use either the VXB or Bearings Direct ones. The Amazon one does not appear to have a grooved race, and the balls appear to be smaller than the others.

I think that either one of the other two will work fine, and both should operate smoothly.
