Nexen Rod Locks 966195 - Manual (Page 5)

5 FORM NO. L-21222-E-1211
1. Apply a constant supply of air, with a minimum of 4.1
bar (60 psi) air pressure to open (release) the Rod
Lock. Manual release option; apply the appropriate
amount of torque to the manual override mechanism
to open (release) the Rod Lock.
2. Remove the supplied rod from the inside of the Rod
Lock and keep for future use.
INSTALLATION
3. Carefully slide the Rod Lock over the cylinder rod
or guide rod, past the seal(s) and through the entire
assembly. Note: Cylinder (“C”) mounts, skip to
instruction #5.
4. “S” (stand-alone) series: Remove the air pressure to
engage the Rod Lock on the guide rod when it is in the
desired position.
5. “C” (cylinder mount) series: Carefully slide the Rod
Lock onto the cylinder rod toward the cylinder end cap.
The Rod Lock is piloted and sealed to the gland O.D.,
so some force is required. Press the Rod Lock onto
the end cap face as close as possible.
6. Using a corner-to-corner sequence, install and tighten
the mounting screws or tie rod nuts to approximately
75% of the final tightening torque. (See Table 1)
7. Using a calibrated torque wrench, tighten the fasteners
or nuts to the final torque specification using the same
corner-to-corner sequence.
8. Remove the air pressure to engage the Rod Lock on
the cylinder rod.
NOTE: “Rod” and “Shaft” refer to the same feature and
are used interchangeably.
The “S” (stand-alone) series Rod Locks are designed to
mount on round guide rods and are typically mounted in
accordance with the design of the machine.
The “C” (cylinder) series Rod Locks are designed to
mount directly to NFPA or ISO flush-mount air cylinders.
The “C” -mounted Rod Locks come with (4) mounting
screws. These screws are used to attach the Rod Lock
to cylinders with tapped holes in the interface or with
socket head, sleeve nuts. The mounting screws are not
necessary on cylinders equipped with threaded tie rods
/ nuts. Cylinders should be prepared with enough rod
length and tie rod length (if appropriate) to accommodate
the rod lock length.
