Installation Guide Linear Rotary Motors
7. Screwing the Rotary Motor to the Linear Motor
After successful assembly of the slider (linear motor) (4), stator (linear motor) (3) and stator (rotary motor)
(2), the two screws (6) opposite each other must be tightened. In the case of a third screw (6), this must be
tightened only at the end.
8.4 Full Maintenance
Complete disassembly of the PR01 motor is only necessary if the stator of the rotary motor (2) has to be
cleaned or the rotary motor ball bearings have to be replaced.
•
A complete disassembly is only to be carried out by NTI AG / LinMot or certified
companies.
•
If the motor is completely disassembled by other companies / persons, a complete loss
of warranty automatically comes into effect.
•
A complete maintenance of the PR01 motor can be ordered under article number r156
from NTI AG / LinMot.
8.4.1 Linear Ball Bearing / Plain Bearing
The linear rotary shaft is guided in the stator of the rotary motor by a linear ball bearing. The linear ball
bearings are of high quality, initially lubricated, shielded from environmental influences and do not require
cyclical maintenance. Linear ball bearings can only be replaced by NTI AG / LinMot in the course of a full
maintenance of the PR01 linear rotary motor (Item-No. r156).
8.4.2 Ball Bearing
High-quality recirculating ball bearings installed in the linear motor are initially lubricated, shielded from
environmental influences and do not require cyclical maintenance. Ball bearings can only be replaced by NTI
AG / LinMot in the course of a full maintenance of the PR01 motor (Item-No. r156).
8.4.3 Air Coupling / Rotary Coupling (Hollow Slider)
Linear rotary motors with option -L (through bore-hole) have an air coupling / rotary coupling between the
slider of the linear motor and linear rotary shaft. Before delivery, the coupling is checked and validated for
leakage. The air coupling can lose its tightness due to influences such as aging, temperature, load cycles,
etc., which can be particularly noticeable in the finest vacuum applications. In such applications it is
recommended to work with a sufficiently large vacuum reserve.
The air coupling can only be replaced by NTI AG / LinMot in the course of a full maintenance of the PR01
motor (Item-No. r156).
8.5 Cleaning Agents / Lubricants
The LU06 cleaning spray is recommended for cleaning LinMot stators and sliders.
LinMot grease LU02 is prescribed to improve the sliding properties between the chromium nickel steel
surface of the slider and the plastic plain bearing.

8.6 Electrical Resistance Test
To check the stators, the ohmic resistances between the individual connector pins can be measured. If the
measured values are outside the tolerance of +/- 10% of the listed values, the stator could be damaged
(listed values measured at 20°C).
