Horizontal
Tolerance table
The rotation speed of the shafts will decide the demands on the alignment. The table
on this side can be used as a guidance if no other tolerances is recommended by the
manufacturer of the machines.
The tolerances is set to the maximum allowed deviation from accurate values, with no
consideration to if that value should be zero or compensated for thermal growth.

The higher the rpm of a machinery is, the tighter the tolerance must be. The acceptable
tolerance is used for re-alignments on non-critical machinery. New installations and
critical machines should always be aligned within the excellent tolerance.
Note!
Consider these tables as guidelines. Many machines must be aligned very accurately
even if they have a lower rpm. For example gearboxes.
