Hey Guys,
We have a large rotating assembly that has a relatively high clearance plain bearing on either end. The plain bearings have a running clearance of about .030" and are 18ft apart. The bearing surface is about 8" diameter and 9" deep.
I am measuring run-out on the shaft ends by placing the entire assembly on pillow block balancing ways. They are placed as in-board on the bearing surface as possible. Then I simply place a dial indicator on the outboard end of the bearing surface and rotate the assembly.
Does this sound like a reasonable way to measure run-out in this situation?
