Horizontal shaft alignment
43
Both the sensor and laser should be at the same height, as low as possible, yet high
enough for the beam to clear the coupling flange. They should also visually appear to
be rotationally aligned to each other.
Make the final adjustments, loosening the brackets slightly if necessary, then rotating
them, and retightening.
In some cases, if the
coupling is large enough,
a coupling bolt can be
removed and the laser
beam shot through the
bolt hole, in order to
avoid protruding radially
beyond the coupling‘s
outer diameter (O.D.).
