Dynamic runout
WebSTBM is associated with the shaft being aligned improperly with the surrounding hardware. Dynamic run out occurs when the shaft does not rotate around its center axis. Both forms of eccentricity cause seals to wear unevenly and leak. High leakage and wear is particularly problematic as shaft speeds and pressure increase.
