● A shift in the position of the axis, if the driving pinions are not axially
fixed on the machine side,
● A thermally dependent component of the axial force, if the driving pin‐
ions are axially fixed on the machine side. There is a risk that the maxi‐
mum permissible axial force will be exceeded or that the backlash within
the gearing will increase excessively.
● Damage to the B-side motor fixed bearing due to exceeding the maxi‐
mum permissible axial force.
Preferably use self-bearing drive elements which are connected
to the motor shaft via axially compensating couplings!
