Mounting information and instructions
The following mounting instructions must be carefully observed:
For high-speed machines, we recommend that the complete unit is dynamically
balanced after couplings or belt pulleys have been mounted.
Use suitable equipment when mounting drive elements. Use the thread at the
shaft end.
Do not apply any blows or axial pressure to the shaft end.
Especially for high-speed motors with flange mounting, it is important that the
mounting is stiff in order to locate any resonant frequency as high as possible
so that it remains above the maximum rotational frequency.
