INSTALLATION
ROD MATERIAL
• Nexen’s Rod Lock must mount to a shaft that is
hardened to a minimum of HRC 60 or hard-chrome
plated to a minimum thickness of 20 microns
[0.0008 in] or damage to the shaft may result.
• The diameter must lie in the h8 tolerance range.

AIR FITTINGS
3. Carefully work the new rod past the seal and
through the rod lock assembly.
4. When the rod is in the desired position, engage the
lock by removing air pressure.
5. A variety of mounting configurations are available;
mount the rod lock as desired. The rod lock unit can
be installed in any orientation.
DANGER
Support the load before disengaging the Rod Lock. Failure to
support the load could result in serious bodily injury.
1. The Nexen rod lock is equipped with a 1/8 inch
NPT port for the air inlet. Route clean air, using soft
or hard lines, supplying at least 4.8 bar [70 psi] to
facilitate full disengagement.
NOTE: Install the valve in close proximity to the Rod
Lock unit for faster engagement and disengagement.
Higher air pressures will also speed the disengage-
ment time, but do not exceed 10.0 bar [150 psi] air
pressure.
2. The Nexen rod lock is equipped with a 1/16 inch
NPT port for the internal vent. If the air quality
around the application is poor, route the vent of the
rod lock to a more suitable area, or use a filtered
breather. Contact Nexen for available components.
NOTE: Clean air is important for proper Rod Lock func-
tioning. Debris inside the rod lock may inhibit perfor-
mance and/or shorten the life of the product.
• The surface roughness Rmax must be 3.2 microns
[16 microinch] or better.
• The rated holding force corresponds to static load
conditions. If the rated value is exceeded, slippage
may occur. Operating dynamic forces must not
exceed the static holding force.

SERVICE
NOTE: The rod lock assembly is designed for extended service life. Due to this long product life, stored spring
energy, and the complexity of the internal components, Nexen recommends that all service be performed by
trained personnel.
Do not attempt to remove the retaining ring and dismantle the rod lock assembly. This product is spring loaded
and under pressure. If the product malfunctions, replace the unit or contact Nexen.
