5.1 General Notes on Installation
NOTICE
Friction due to lateral forces!
Lateral forces that act on the fine-thread screw and the ball tip of the linear actuator increase
the friction on the internal drive components. Increased friction impairs the motion of the fine-
thread screw and increases the wear of the drive components.
 Avoid lateral forces on the fine-thread screw and on the ball tip of the N-472.
 Install the N-472 so that the fine-thread screw is aligned vertically to the contact surface of
the moving part of the mechanical mounting.
NOTICE
Increased wear due to friction!
Increased friction on the contact surface between the ball tip and the moving part of the
mechanical mounting increases wear.
 Make sure that the contact surface of the mechanical mounting has a roughness of
R <0.1 µm and a hardness of at least 500 HV (corresponds to hardened steel).
a
 Optional: Decrease the friction by applying a small amount of lubricant to the contact
surface of the mechanical mounting.
