INTRODUCTION
Nexen’s Linear Actuators provide the thrust that is required to move an unwind stand, a wind up roll stand or to convert an
existing hydraulically actuated web guiding mechanism to electrical actuation.
Nexen’s Linear Actuators are available in several models with different strokes.
To ensure optimum response and accuracy, roll stands should be mounted on linear ball bearings. Sliding ways and wheel
track systems have higher coefficients of friction which requires greater break away thrust. Greater break away thrust
prevents accurate, minute corrections.
INSTALLATION
NOTE: Refer to Figure 1
1. Attach the Mounting Base bracket to a fixed member
of the guiding mechanism.
2. Connect the Clevis End to the moveable member of
the guiding mechanism.

NOTE: If the Linear Actuator moves in the wrong
direction, then reverse the wire lead
connections.
2. Connect the Limit Switch leads to the Limit Switch
terminals of the Web Guide Controller as follows:
Red lead to Extension.
Black lead to Retraction.
Green lead to Common.
Shield lead to Shield.
CAUTION
Do NOT use the Linear Actuator for Radial
(side) loads.
The Linear Actuator is designed for axial
(thrust) loads ONLY.

NOTE: Refer to Figures 3, 4
The limit switches factory default setting are for the maximum
stroke.
1. Turn the Web Guide Controller to "ON" and place it
in the manual mode.
2. Carefully remove the Rubber Sealing Strip from the
Limit Switch Housing.
3. Press the button on the Web Guide Controller that
extends the Linear Actuator until the desired extension
position is reached. Refer to your controller manual for
specific details.
4. Use a screwdriver to loosen the Clamping Screw on
the Extension Limit Switch.
5. Slide the Extension Limit Switch toward the Retraction
Switch until the Web Guide Controller indicates that
the switches have changed state.
6. Tighten the Clamping Screw on the Extension Limit
Switch.
7. Press the button on the Web Guide Controller that
retracts the Linear Actuator to the desired retraction
position. Refer to your controller manual for specific
details.
8. Use a screwdriver to loosen the Clamping Screw on
the Retraction Limit Switch.
9. Slide the Extension Limit Switch toward the Retraction
Switch until the Web Guide Controller indicates that
the switches have changed state.
10. Tighten the Clamping Screw on the Retraction Limit
Switch.
11. Replace the Rubber Sealing Strip in the Limit Switch
Housing.
CAUTION
If there is a physical obstruction or stop, then the
Limit Switches MUST be adjusted to interrupt
the Linear Actuator's movement before contact
is made with the physical obstruction or stop.
Failure to adjust the Limit Switches will damage
both the Linear Actuator and the Web Guiding
Mechanism.
If there is no physical obstruction to travel, then
the Limit Switches may be left in their factory set
default positions.
