Probably 80% of rotors making their way to a service shop have
eccentricities outside of the
guidelines given in ISO 1940. These generally
come in the form of shaft bows, off-square or
eccentric couplings, or misaligned
journals, and if left ignored can create innumerable vibration
problems in operation. Identifying these faults through runout data evaluation is key.
Out-of-tolerance couplings and journals must be corrected by machining. Rotor bows can often
be resolved using our
proprietary balancing method alone, which has been specifically developed
for balancing distributed mass eccentricities.
