WEG MOTORS ARE DYNAMICALLY
BALANCED, WITH HALF KEY AT NO LOAD
AND UNCOUPLED.
Ensure that the motor mounting devices do not allow
modifications on the alignment and further damages to the
bearings.
When assembling a half-coupling, be sure to use suitable
equipment and tools to protect the bearings.
Suitable assembly of half-coupling: check that clearance Y
is less than 0.05mm and that the difference X1 to X2 is less
than 0.05m as well.
Transmission elements such as pulleys, couplings, etc must
be dynamically balanced with half key before installation. Use
always appropriate tools for installation and removal.
