CHAPTER 2 - Technical specification
MANIU04.9607 GB 03/97
Page 2.2
Table 2/2 contains, for each servomotor, values of axial and radial loads that must not be
exceeded to guarantee a regular lifetime of about 20000 hours in continuous duty of the
bearings with permanent lubrication. In general, a locked bearing is assembled on the motor
A-side.

Notes:
(1) Values for simultaneous axial and radial stresses are available on request.
(2) Values for versions with integrated brake (special versions) are available on request.
(3) Values for admissible axial loads are valid for force direction F
A
towards the motor; for the opposite direction a
reduction is necessary (values available on request).
CAUTION: Taking into account the foreseen duration, the radial laads F
R
must not exceed
the values indicated, even for a transient period (acceleration, deceleration). In
particular, shocks provoked for example by the assembling of mechanical parts
(couplings, key nuts, etc ... ) on the shaft end are not allowed.
