If accessories are mounted on the piston rod:
• Use the following elements:
– only the thread of the piston rod.
– the square piston rod 5 for counter pressure
(only in the retracted end position).
The maximum torque on the bearing must not exceed 5 Nm.
– an external guide for the work load.
This will prevent lateral loads on the piston rod.
Lateral loads produce false measurement results and may
damage the measuring system.
