DOK-MOTOR*-MAD/MAF****-PR03-EN-P
For all attachments of drive elements to the drive shaft, such as
• gearboxes
• couplings
• pinions
it is imperative that the following notes are observed.
Generally, overtermined bearings are to be avoided by all means when
connecting drive elements. The tolerances inevitably present in such
cases will lead to additional forces acting on the bearing of the motor
shaft and, should the occasion arise, to a distinctly reduced service life of
the bearing and/or to fatigue transverse rupture/vibration rupture of the
motor shaft.
