n order to accurately align two machines with each another, the
position of their shafts must be measured by measuring radial
displacement (such as ROTALIGN does) while the shafts are rotated.
Unfortunately, some machines do not fulfill this requirement as their
shafts cannot be rotated slowly for measurement. Especially when
long separations between machines are involved, this condition
compromises alignment accuracy when conventional measurement
methods are used. See "Pass" measurement mode, page 4-36.
However, the ROTALIGN magnetic sliding bracket offers an elegant
solution to this dilemma. The bracket fits onto the coupling flange as
shown and simply slides around to the required measurement
positions. Its powerful magnets ensure the mounting stability needed
for accurate measurement. The magnetic sliding bracket for station-
ary shafts is suitable for all shaft diameters over 80 mm (3 1/8").
Anytime shafts cannot be rotated during measurement (regardless
what method is used), alignment accuracy becomes dependent on
angular positioning accuracy and machining quality of the shaft and
coupling:
■ The flange and perimeter of the coupling or shaft must be
surface-finished.
■ The coupling or shaft must be made of ferrous material (steel)
with a large magnetic contact area over which the magnets can
guide the bracket.
