clearance between shaft and shaft hub
clearance between shaft and shaft hub
(OP)
hello all!
Can a high clearance between the shaft and the shaft hub lead to high vibration levels? And does it appear in the espectrum as 1x only ?
thank you in advance!

But The change in centering of a formerly well "balanced" part CAN and WILL result in some greater amount of unbalance.
Note that eccentricity or change in centering of a mere 0.0015" uses up the entire G6.3 tolerance at 1800 rpm.

Shaft runout, resulting from shaft > ball/roller bearing fits or actual shaft runout also eagerly conspire to move even a snug fitting rotor off the rotating axis of the balance arbor, often making the "Precision electronic balanced" sticker pretty misleading.
