So I'm designing something. And I figured a bearing for what I wanted would be pretty easy to find. But, I can't figure out what exactly to call this type of bearing. Or figure out if what I've expected to find actually is available. It could be just a case of not searching for the exact right thing to find what I need.I made a gif of the sort of thing I'm imagining.Part sizes are flexible because I'm building the whole design around finding this first. I need to perform the following action: Pipe A is a standing pipe that holds platform where an object sits. It bears weight, so it'd likely be at few inches in diameter. I need to clamp an arm to that standing pipe that can spin freely around the object. Pipe B doesn't have to be a pipe at all really, it won't hold a great deal of weight, so material is flexible.Really the image I have in my head isn't that important. I just need to perform the action described. Figure the object on the platform will be a couple hundred pounds. And the arm that rotates around it needs to flow freely and smoothly. The platform and object can't move. via /r/DIY https://ift.tt/2zbMYHq
