I have a steel cone, it's not heavy, perhaps 80kg empty. I have to support it on rollers so that it can rotate about its axis at about 20rpm.
This is one I've used briefly. The support rollers work however in my opinion metal passing each end of the roller is travelling at a different speed drawing unnecessary power to drive it and creating wear.
The apex of the cone will be supported by a 30mm self-aligning bearing. The support rollers will spaced sufficiently apart to keep it running true.
Now where do I place my rollers?
Option 1 will have them running true to the axis.
Option 2 will be directly under the load but not aligned with the axis.
Option 3 might be to go with option 1 and add a thrust roller facing NE under the top lip?
Keep in mind, I rarely do as I'm told
