● When mounting or withdrawing, do not apply any blows, for example with a hammer or
similar tool, to the parts to be mounted or withdrawn.
● Only transfer radial or axial forces specified in the catalog to the motor bearings via the
shaft extension.
Machines with type of construction IM B15, IM B9, IM V8 and IM V9
Types of construction without bearings on the drive side
These machines do not have their own bearing system for the machine shaft at the drive end
(DE). The machine shaft is accepted by the (hollow) shaft or coupling of the system or driven
machine.
● Using the centering edge, the machine is aligned with respect to enclosures, flanges or
driven machines.
● Note that the temperature of the motor and motor shaft increases during operation. The
thermal expansion of the machine shaft must be compensated by the customer by
applying suitable measures.
Use the spring washers provided to locate the NDE bearing without any play.
Material damage can occur if the following notes are not carefully observed:
• The IM B3 bearing shield with integrated distance ring mounted at the drive end (DE) is
only used transport lock. A warning label is attached to this bearing shield.
• The spacer ring is not a roller bearing.
• Remove the bearing shield and the spacer ring.
• Remove the transport lock before commissioning.
Note
Only authorized retrofit partners must be employed to
relocate the bolted on mounting feet at
the machine enclosure.
