Mechanical system
The mounting dimensions can be checked before mounting the motor,
e.g. using the final dimensions and feeler gauges.
The mounting dimensions must lie within the specified tolerance band-
width over the complete traversing distance.
Note
The valid mounting dimensions can be taken from the following
literature:

The data sheet of the appropriate motor
For mounting dimension and air gap, the following applies:
Only the mounting dimension is decisive and not the air gap which can
be measured, when it comes to maintaining the electrical and
system–related characteristics of the linear motor. The air gap must be
large enough so that the motor can freely move.
