Features and functions
The following boundary conditions apply to the
bearing service life L :
10h
•
Operation within the specified permissible
loads (radial and axial force)
•
Operation within the permissible ambient
conditions (temperature range 0 ... 40 °C,
vibration, and so on).
•
Operation within the thermally permissible
operating characteristic curve
The bearing lifetime also depends on the service
life of the grease. A calculated grease service life
was used for the mentioned specifications, taking
into consideration the following boundary condi-
tions.
•
Horizontal installation
•
Low vibration and impact loads
•
No oscillating bearing movement < 180°
•
Mean speed according to the following table

The following standard values apply under the
specified preconditions:
L = 30.000 h, in case of utilization after
10h
S1-60K and max. load factor 95% during the run-
time.
Remark: When exceeding or not complying
with these conditions, a reduced service life is to
be expected.
Explanation of radial and axial force
During operation, both radial and axial forces act
upon the motor shaft and the motor bearing. The
permissible radial force F
shaft shoulder and the mean speed is specified in
the radial force diagrams.

6.2.11 Frame size, installation type

The motors can be installed horizontally and ver-
tically with the shaft end pointing to the top or
bottom. The mounting variants comply with the
IM code according to EN 60034-7 for design and
installation type.
