L-220 Linear Actuator MP149E Version: 1.3 15
5.3 Installing the Linear Actuator in a Mechanical Mounting
NOTICE
Incorrect tightening torque of the mounting nut!
The motion of the pusher can be hindered by a mounting nut that has been tightened too
strongly. This reduces the positioning accuracy.

Tighten the mounting nut to a maximum torque 10 Nm.
INFORMATION
To achieve an optimum repeatability, the mounting shaft must not have any backlash.
During mounting, make sure that there is a faultless connection between the actuator and the
mechanical mounting.

We recommend installing the actuator in the mechanical mounting with a clamp connection.
The following instructions refer to this case.
Requirements
