This product is capable of emitting
a spark if misused therefore is not
recommended for use in any explosive
environment.
WARNING
Ensure proper guarding of the product is

5FORM NO. L-21089-C-0914
INSTALLATION
1. Before mounting, ensure Rear Piston Plate (Item 3)
has adequate clearance to move freely (See Figure 1
& Table 1).
2. Remove any dirt, grease, or foreign material from the
Friction Disc Hub (Item 1) bore and the tapered surfaces
of the Q.D. Bushing.
NOTE: Do not use lubricants when installing Q.D.
Bushing.
Do not strike Q.D. Bushing to “set” it in the bore of the
Friction Disc Hub.
3. Slide Q.D. Bushing into the bore of the Friction Disc
Hub (Item 1) (See Figure 2).
4. Insert cap screws into Q.D. Bushing, aligning them with
the tapped holes in the Friction Disc Hub (Item 1) (See
Figure 2).
5. Position TSE Brake on the shaft (See Figure 2).
6. Alternately and evenly tighten Q.D. Bushing cap screws
to the recommended torque (See Table 2).
NOTE: There should be a 1/4" - 1/2" [6.4 - 12.7 mm]
gap between the Q.D. Bushing flange and the Friction
Disc Hub after the cap screws have been tightened to
the recommended torque.
Runout is minimized if a Dial Indicator is used as the
Q.D. Bushing cap screws are tightened. Place contact
tip of Dial Indicator on smooth surface of the Friction
Disc Hub (Item 1) to measure runout. Runout on this
surface must not exceed 0.005" [0.13 mm] TIR when
cap screws are tightened (See Figure 2).
7. Secure brake Air Chamber (Item 4) to prevent
rotation and take up brake torque. A torque pin slot
is provided in the Air Chamber flange (See Figure 2).
NOTE: Keep torque pin as short as possible.

FORM NO. L-21089-C-0914
NOTE
Nexen pneumatically actuated devices require clean, pressure regulated air for maximum performance and
life. All seals in Nexen pneumatically operated devices are lubricated for 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 product, and use low viscosity oil such as SAE-10.
Synthetic lubricants are not recommended.
Nexen product's bearings are shielded and pre-lubricated, and require no further lubrication.
LUBRICATOR DRIP RATE SETTINGS
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.
LUBRICATION
CAUTION
These settings are for Nexen supplied
lubricators. If you are not using a Nexen
lubricator, calibration must follow the
manufacturer's suggested procedure.
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.
BRAKE GUARD INSTALLATION
NOTE: Refer to Figure 3.
1. Align the mounting holes of the Brake Guard with the
four tapped holes in the TSE Mounting Flange.
2. Using the four 10-24 Phillips Head Pan Screws, secure
the Brake Guard to the TSE. Tighten to 35 in-lbs [4
Nm].
3. If the Brake Guard is not through shaft mounting, place
the End Cap over the front of the Brake Guard and bend
the tabs around the Brake Guard to hold the End Cap
in place.

OPERATION
Apply increasing amounts of air pressure to the brake until
the Friction Disc Hub turns freely.
The TSE Brake will remain engaged until sufficient air
pressure is applied to release it. The amount of release air
pressure may vary depending upon the length of the air lines,
amount of springs, and the type of controls used.

AIR CONNECTIONS
NOTE
For quick response, Nexen recommends a quick exhaust
valve and short air lines between the Control Valves and
the product. Align the air inlet ports to a down position
to allow condensation to drain out of the air chambers
of the product.
CAUTION
Low air pressure will cause slippage and
overheating. Excessive air pressure will
cause abrupt starts and stops, reducing
product life.
All Nexen pneumatically actuated devices require clean
and dry air, which meet or exceeds ISO 8573.1:2001
Class 4.4.3 quality.
The following is a common air supply scheme used with
this product. This is an example and not an all-inclusive
list. All air circuits to be used with this product must be
designed following ISO 4414 guidelines.
CAUTION
To avoid unnecessary loading of components,
Nexen recommends not exceeding the air pressure
required to release the brake. The brake seals,
however, have been designed to tolerate up to 7.6
bar (110 PSI) of continuous pressure.
WARNING
Never exceed maximum operating
speeds listed for your product.
(See Table 3).
CAUTION
The temperature limits for this
product line are 4.5-104 Degree
Celsius (40-220 Degree F).
CAUTION
Never exceed life of facing material. Facing
life depends on the volume of material and
the total energy over the life of the unit.
Expected life (in hrs) can be found by:
Time=Volume/(Power*Wear Rate).
TABLE 3
Sizes: Max RPM
TSE 1200-1400 *1800
*Consult Nexen for high speed applications.
WARNING
Ensure proper guarding of the product is
used. Nexen recommends the machine builder
design guarding in compliance with OSHA 29
CFR 1910 “Occupational Safety and Health
Hazards”.

FORM NO. L-21089-C-0914
NOTE: Periodically inspect all mounting bolts and air line
fittings to make sure they are securely tightened. Pay
particular attention to the Flange Head Hex Screws (Item
6 or 16). If these screws are loose, the Piston Plate (Item
3) travel will increase, causing the O-ring Seals to leak air.
Tighten the Flange Head Hex Screws (Item 6 and16) to
the recommended torque (See Table 4).
Inspect Friction Facings (Item 5) for signs of wear and
replace if worn down to where the Machine Screws (Item
14) may score the Friction Disc Hub.

MAINTENANCE
MANUAL DISENGAGEMENT
1. To manually release the TSE Brake, first the air pressure
supply must be removed. (See CAUTION)
2. Remove the Flange Head Hex Screws (Item 16) from
the Piston (Item 2) and the Socket Head Cap Screws
(Item 6) from the opposing Piston Plate (Item 3).
3. Remove the Piston Plate (Item 3) and all three Spacers
(Item 15).
4. Replace Piston Plate (Item 3) and Socket Head Cap
Screws (Item 6) with longer customer supplied fasteners
(SAE Grade 8, 3/8-16) at least 4" long (TSE 1200)
and 5" long (TSE 1400). Cap screws must be long
enough, with sufficient thread length, to allow full removal
of spring force. Spring travel has been designed to
engage over entire area of friction material. Tighten
Cap Screws alternately and evenly to draw the Piston
Plate (Item 3) and Friction Facing (Item 5) away from
the Friction Disc-Hub (Item 1).

FURTHER DISASSEMBLY IS NOT RECOMMENDED
Due to complicated assembly and the large amount of spring force, Nexen recommends that
all further disassembly or reassembly be completed by a factory professional. Units should be
sent directly to the factory for repairs or service.

Snap Ring on Hub-Disc when removing Rear
Piston Plate and Piston Assembly. Always
wear safety goggles when working with spring
or tension loaded fasteners or devices.

and exclusions set out in the drawing. NEXEN MAKES NO OTHER WARRANTY, EXPRESS OR IMPLIED, AND ALL
IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION, IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE ARE HEREBY DISCLAIMED. This warranty applies only if: (a) the Product has
been installed, used and maintained in accordance with any applicable Nexen installation or maintenance manual for the

overages and nonconformities not reported to Nexen as required by this section will be deemed waived.
Limitation on Actions
No action, regardless of form, arising out of any transaction to which these terms and conditions are applicable may be
brought by the Buyer more than one year after the cause of action has accrued.
