LUBRICATION
Note: Nexen pneumatically actuated devices require clean, pressure regulated air for maximum performance
and life. Nexen pneumatically operated devices pneumatic seals are lubricated life, and do not require
additional lubrication.
However, some customers prefer to use an air line lubricator, which injects oil into the pressurized air,
forcing an oil mist into the air chamber. This is acceptable, but care must be taken to ensure once an air mist
lubrication system is used, it is continually used over the life of the product as the oil mist may wash free the
factory installed lubrication.
Locate the lubricator above and within ten feet of the Torque Limiter, and use low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.
LUBRICATOR DRIP RATE SETTINGS
NOTE: Settings are for Nexen supplied lubricators. If you are not using a Nexen lubricator, calibration must
replicate the following procedure:
1. Close and disconnect the air line from the unit.
2. Turn the Lubricator Adjustment Knob
counterclockwise three complete turns.
3. Open the air line.
4. Close the air line to the unit when a drop of oil forms
in the Lubricator Sight Gage.
5. Connect the air line to the unit.
6. Turn the Lubricator Adjustment Knob clockwise until
closed.
7. Turn the Lubricator Adjustment Knob
counterclockwise one-third turn.
8. Open the air line to the unit.
Nexen’s Torque Limiter bearings are shielded and pre-
lubricated, and require no further lubrication.
The Drive Flange Assembly has been pre-lubricated and
does not require additional lubrication at start up. The
amount of lubrication is sufficient to maintain the proper
coefficient of friction at the Balls and Detents.
The Drive Flange Assembly must be disassembled
if lubrication becomes necessary (See PARTS
REPLACEMENT). Spread recommended lubricants
evenly (about 1/8" [3.2 mm] thick by 1/8" [3.2 mm]
wide) over Drive Flange Balls, Ball Track, and Drive Ring
Detents (See Table 6 for recommended lubricants).

RECOMMENDED LUBRICANTS
Chevron SRI
Amoco Rykon Premium Grease #2
Exxon Unirex #2
Shell Dolium Grease #2
Texaco Premium #2
CAUTION
Do not over-lubricate the Drive Flange
Assembly. Over-lubrication creates a
hydraulic effect within the Torque Limiter that
will adversely affect the break-away torque.
