Under Balancing, various preferences (or unfortunate obligations) are dealt with to better document and understand machine behavior during this corrective operation. Metric or Imperial units are readily available for all functions. Grade refers to ISO 1940 and to permissible residual imbalance as defined by the user if so desired.

When performing alignment related work, the calculations relating to bar sag, an often neglected occurrence, and thermal growth, when “hot” alignment is impossible, should be documented properly. Do remember that OPERATIONAL CONDITIONS may impose stresses that will displace certain machine components from their position at rest. Also keep in mind that for machinery of significant size GROWS into alignment, hence, severe vibration observed at start-up while the machine remains cold should ease up as components reach proper positioning.

This particular table enables definition of the specific levels deemed excessive by the END USER. Do remember that it has become standard practice to define CORPORATE and purchasing acceptance testing expectations that usually exceed and go far beyond the established standards.
