ATTENTION
If the permissible operating speed is exceeded
this has a detrimental effect on the unit's operat-
ing characteristics:
 higher noise levels
 heavy vibrations
 reduced grease useful lifetime
 reduced time between changing bearings
The maximum speed should not be exceeded,
as damage can result from higher operating
speeds.
