2) A bearing that size that can run 20,000 is only a bathed bearing.
3) using a smaller (next size Down) ZZ bearing with shims will sustain 20,000rpm all day long. Need different stud/shaft. Plus shim in pulley.
4) this is most important! You have all asked Jerry what he's going to do. Rather than having him spend all his time answering all these worthless argumentitive guestions let him get to the point at hand.
The answer is simple but it will take some effort and can anyone blame him for trying to solve EVERYONES' problem at an affordable price. So many of you make it more than obvious you have never had a true custom part made by a machine shop or you would realize how fast the costs can go right through the roof.
Now I don't need everyone sending me statements of how much they or someone else has done in the past. Just as most of the last 13 pages of this blog it just doesn't matter.
Let Jerry handle things if you are expecting him to take care of it for you.
