Throughout this manual there are a number of
HAZARD WARNINGS that must be read and adhered to in order to prevent possible personal injury and/or damage to equipment. Three signal words
“DANGER”, “WARNING”, and “CAUTION” are used
Danger
Denotes the most serious hazard, and is used when serious injury or death WILL result from misuse or failure to follow specific instructions.
Used when serious injury or death MAY result from misuse or failure to follow specific instructions.
Used when injury or product / equipment damage may result from misuse or failure to follow specific instructions.
It is the responsibility and duty of all personnel involved in the installation, operation, and
maintenance of the equipment on which this device is used to fully understand the ! Danger ! Warning and ! Caution procedures by which hazards are to be avoided.
1.1 Description 1.1.1
The Airflex Model DBBS brakes were designed for heavy-duty industrial applications where spring set (power off) braking is required.
1.1.2
All Airflex DBBS brakes are supplied with long wearing, Non-Asbestos Friction material and solid cast, rotating discs.
1.1.3
Airflex DBBS brakes are available in four basic sizes and can be supplied as single, dual, triple or quadruple disc units. The model number identifies the number of discs and the disc diameter. For
example, 225DBBS indicates the brake uses two 25 inch diameter discs. When size, such as 25DBBS is referred to in this manual, it means that the
information given applies to all DBBS models using 25 inch diameter discs; i.e. 125DBBS, 225DBBS, etc...
1.1.4
This manual includes metric equivalents usually shown in parentheses ( ) following the U.S.
measurement system value. Be sure to use the correct value.
1.2
How It Works
1.2.1
Referring to Figure 1 and Table 1, the gear (28) is mounted on the shaft which is to be stopped. The brake assembly is attached to the machine frame or reaction bracket. As air pressure is applied through the ports in the cylinder (19), the cylinder and pressure plate (14), which are attached to each
other with screws (20), flat washers (17.) and spacer tubes (27.), move away from the mounting flange (2), which is connected to the machine frame or reaction bracket. The pressure plate compresses the springs (22) (52) against the stationary spring housing (16) and the clamp force is removed from the discs (58) which ride on the gear. The shaft is then free to rotate.
1.2.2
As air pressure is exhausted, the springs (22) force the pressure plate (14) toward the mounting flange (2), clamping the rotating discs (58) between the stationary friction discs (8) which are attached to the pressure plate (14) and mounting flange (2). On two, three and four disc models, a reaction plate (31), to which friction discs are mounted, and an additional disc are clamped between the pressure plate and mounting flange.
2.0 Installation
Danger
Prior to installation of the DBBS brake, make sure that the machinery will remain in a secured position. Failure to do so could result in serious personal injury or possibly death.
2.1 Alignment 2.1.1
For proper operation and service life, the DBBS brake must be mounted concentric and at right angles to the shaft within the limits shown on Table 2.CAUTION
Proper alignment is necessary to assure that the discs (58) will track properly. Improper alignment will result in excessive wear to the friction discs (8), discs (58) and gear (28). See Figure 2.
DBBS Brakes
1.0 Introduction
EATON Airflex ? DBB 8110 Brake Assembly E-CLCL-TT001-E December 20127
2.1.2
To aid in obtaining accurate readings, a rigid bracket should be fabricated for mounting a dial indicator when checking alignment.
2.1.3
Bearing or machinery manufacturers may require different alignment tolerances. Use the tightest of those recommended.
2.2 Mounting
Support brackets for external stud support may be required for specific brake models. See Table 3 for models requiring support brackets. Consult Eaton
Airflex Engineering for design parameters. Warning
Failure to properly support studs as noted in Table 3 may result in drastic loss of torque, brake damage and brake failure.
2.2.1
Ensure that the shaft is clean and free of nicks or burrs and that the key fits properly in the shaft and
gear. Tap the key into the shaft keyway.
2.2.2
On multiple disc brakes, before installing the gear onto the shaft, slide it into the brake assembly to align the splines on the discs. Air pressure must
be applied to the brake to release the discs for
alignment. Once the gear passes through all discs, exhaust the air to clamp them into position and remove the gear.
Warning
Maximum allowable air pressure is 120 psig (8.2 bar) for sizes 20DBBS, 25DBBS and 38DBBS. Maximum allowable air pressure is 150 psig (10.3 bar) for the 50DBBS. Application of pressure exceeding maximum allowable may result in damage to the brake.
2.2.3
Apply a light coat of anti-seizing compound to the shaft.
2.2.4
To install the gear, heat uniformly to approximately 250°F (121°C), prior to pressing the gear onto the shaft. Making sure the dimension between the gear and brake mounting surface (“A”) is held at 1.00” (25.4) for sizes 20DBBS, 25DBBS and 38DBBS and 2.00” for size 50DBBS. See Figure 1.
Do not allow the gear temperature to exceed 350°F (17.6°C). Overheating the gear will adversely affect the hardness and wear life.
2.2.5
Apply a light coat of Castrol Molub-Alloy 936SF Heavy grease or equivalent to the gear teeth and slide the brake assembly onto the gear.
Note
For reference, Eaton Airflex part number for the specified grease is 000153X1182.

82.2.6
While supporting the brake, connect an air supply and apply enough pressure to release the brake.
Attach the mounting flange (2) to the brake mounting surface using the appropriate fasteners. Torque the fasteners to the specified value. See Table 4. Note
Mounting holes in the 325DBBS and 425DBBS brakes are larger than the 125DBBS and 225DBBS sizes. Be sure to use the correct size fasteners.
Use only the proper number and grade fasteners
shown in Table 4. Use of commercial grade fasteners where Grade 8 fasteners are specified may result in failure of the fasteners and a sudden and drastic
reduction in brake torque.2.3
Air Supply System
Maximum allowable air pressure is 120 psig (8.2 bar) for sizes 20DBBS, 25DBBS and 38DBBS. Maximum allowable air pressure is 150 psig (10.3 bar) for the 50DBBS. Application of pressure exceeding maximum allowable may result in damage to the brake components.
2.3.1
Cylinder port size is 1/2”-14 NPT for sizes 20 and 25DBBS brakes, 3/4”-14 NPT for size 38DBBS brakes and 1”-11-1/2 NPT for size 50DBBS brakes.2.3.2
Since the air control arrangement will vary from one application to the next, a specific description cannot be presented here. Following are some general guidelines for installing the air control components.
2.3.2.1 Use full size piping consistent with the control valve
size. All piping should be free of metal chips, cutting compound, and any other foreign matter. Pipe ends should be reamed after cutting to eliminate possible restrictions.2.3.2.2 Keep the number of elbows to a minimum to ensure
consistent response.2.3.2.3 Spool type solenoid valves are not recommended.
Use poppet type valves and locate them as close as possible to the brake.
If the DBBS brake is being used on a mechanical power press, special valving may be required.
2.3.2.4 If the DBBS is being used on a cyclic application,
an air receiver tank should be installed in the air supply line and isolated (check valve) from other air consuming equipment.2.3.2.5 The final connection to the brake inlet ports must be
made with flexible hose.2.3.2.6 The DBBS brake does not require lubricated air;
however the solenoid valve may. Consult the valve manufacturer.2.3.2.7. A pressure switch should be located in the air supply
line to the brake and interlocked with the equipment electrical controls.
Before modifying air supply lines, adding inline components or adding pressure switch interlocks, ensure brake will function in a safe manner.

3.0 Operation
3.1 Pressure and Speed Limits
3.1.1
Maximum allowable pressure is 120 psig (8.2 bar) for sizes 20DBBS, 25DBBS and 38DBBS. Maximum allowable air pressure is 150 psig (10.3 bar) for the 50DBBS.
Maximum applied pressure is 120 psig (8.2 bar) for
sizes 20DBBS, 25DBBS and 38DBBS. Maximum allowable air pressure is 150 psig (10.3 bar) for the 50DBBS. Operation at pressures exceeding
maximum may result in damage to the DBBS components.
3.1.2
Maximum freewheeling disc speeds are shown on Table 5.
Operation at disc speeds exceeding the maximum allowable, as shown on Table 5, may result in personal injury or product/equipment damage.
3.2 Initial Operation
3.2.1 Wear-in/Burnishing
3.2.1.1 In order to improve initial operation and brake torque,
it is suggested that the non-asbestos friction material used in the DBBS brakes be worn-in prior to normal operation to improve contact of the mating friction surfaces.
Machine operation should be monitored closely until the friction couple wears in.
3.2.1.2 The shaft on which the brake discs are mounted
should be free to rotate to allow for run-in. On drawworks applications, disconnect the wire rope from the drawworks drum to allow operation as described in the following paragraphs.

103.2.1.3 Release the brake by applying full release pressure
through the ports in the cylinder (19) to allow the brake to freely rotate.
Maximum applied pressure is 120 psig (8.2 bar) for
sizes 20DBBS, 25DBBS and 38DBBS. Maximum allowable air pressure is 150 psig (10.3 bar) for the 50DBBS. Minimum releasing pressure for low
pressure brakes is 60 psig (4.1 bar).
3.2.1.4 Run the motor to achieve a brake disc speed listed in
Table 6. Rapidly exhaust the air pressure in the brake to the pressure listed in Table 6. Slip the brake for the time specified in Table 6, but DO NOT ALLOW
THE BRAKE TO SLIP FOR MORE THAN THE TIME SPECIFIED.Caution
Slipping the brake at increased time intervals, speeds, pressure or temperatures other than
specified may result in damage to brake components.Caution
Brake pressures listed in Table 6 are for the standard compliment of power springs in the DBBS brake. The standard quantity is listed in Table 6. If a brake contains less than the standard compliment of
springs, consult Eaton/Airflex engineering for proper brake pressure to wear-in the brake and spring quantity if unknown for the specific brake.
3.2.1.5 After the brake has engaged/slipped for up to the
maximum slip time specified in Table 6, quickly apply full air pressure to completely release the brake. Smoke rising from the brake should be expected. Freewheel the brake discs at speeds up to the maximum freewheeling speed in Table 6 to allow the brake discs to cool to a temperature at or below 120°F (49°C) use of fans or clean, dry compressed air can be used to accelerate the cooling process.Caution
Use proper safety precautions when using forced ventilation.
Note
The brake pressure listed in Table 6 should provide a dynamic torque target value as listed and resultant power target at the brake speed listed. Since new friction torque will be lower at the start of wear-in procedure, pressure may need to be lowered to achieve the target torque. An adequate control and torque monitoring system must be used if pressure values less than those listed are used for wear-in. Target torque should be monitored to correspond to values listed.
3.2.1.6 Monitor the brake discs temperature during
slipping and cooling. Do not allow the brake discs temperature to exceed 250°F (121°C).3.2.1.7. Repeat steps 3.2.1.3 through 3.2.1.6 for the number
of cycles shown in Table 6 to allow for adequate wear-in of the brake. Allow the brake disc to completely cool to ambient temperature prior to
testing the torque capacity of the brake or returning it to service.3.2.2
If the brake engagement appears harsh, a flow
control valve may be installed in the brake air supply line. When using a flow control valve, install so free flow is to the brake and restricted flow is away from the brake.
Excessive restriction of the brake exhaust air will result in long stopping times and inconsistent
stopping position. Consult Eaton Airflex Engineering with questions.
3.2.3
If the DBBS brake is used in combination with a clutch, clutch/brake overlap may occur which will result in excessive heat generation and motor
overload. Overlap may be detected by monitoring the drive motor current at the beginning and end of each machine cycle. A current surge at the beginning of the cycle usually indicates clutch overlap which can be corrected by restricting the air flow to the clutch or increasing the air pressure to the brake. A current surge at the end of the machine cycle usually indicates brake overlap (see Figure 3) which can be corrected by installing and adjusting a flow control valve in the brake air supply line, as indicated in 3.2.2.

3.3 Periodic Inspection
3.3.1
As the friction material wears, the brake torque will be reduced somewhat and adjustment of the stopping position controls (flow control or limit switch) will be necessary. See the Maintenance section for the friction material wear limit and replacement procedure.
3.3.2
Periodically inspect the brake for proper operation
particularly if excessive heating of the disc (58) has
been experienced or is suspected of having occurred.
See ‘WARNING’ below. Excessive heating of brake components can be caused by disc dragging, excessive E-Stops, low air pressure, warping of the discs, or operating the brake beyond its designed capability.
If the brake is subjected to heat, the discs (58) may
shrink causing a condition whereby the discs will get
stuck to the gear, limiting the axial movement. This
condition will cause failure of the brake to develop
full torque. Warning Failure to develop full torque can cause drastic
equipment failure, personal injury and/or death.
3.3.3 Periodically check for air leakage in the area of the
piston seals (21, 23). For replacement, refer to the
Maintenance section.
3.3.4 Periodically observe the discs with the brake released. Causes of dragging discs may include wear or contamination of the gear or disc splines, disc imbalance, warped discs, or excessive shaft float.
3.3.5
Pneumatic and electrical control interlocks should be periodically checked for correct settings and operation.
3.3.6
Periodically remove the brass drain plug (105) and purge condensation from the cylinder. Replace the brass drain plug with sealant and check for air leaks.
4.0 Maintenance
Prior to performing any maintenance on the DBBS brake, make sure the equipment is in, and will remain in, a safe condition. Never service a brake supporting a load.4.1
Wear Limits
4.1.1
Wear limits for the DBBS components are shown on Table 7.. If any wear limit has been reached or exceeded, that component must be repaired or replaced.
4.2
Wear Adjustment
Note Refer to Figure 4 for illustration of the friction
material wear groove for the size 20DDBBS, 25DBBS and 38DBBS brakes and friction material wear step in the size 50DBBS brakes. Refer to Figure 6, Figure 7., Figure 8 & Figure 9 for an illustration of the wear gaps on all DBBS sizes. On single and multiple disc
units, the friction material must be replaced when
worn to the bottom of the groove on the friction
material or to the bottom of the step on the friction lining on the size 50 brakes. Multiple disc brakes, however, are manufactured with wear spacers that allow for wear adjustment when the ‘Gap Required for Adjustment’ has been reached per the values
in Table 8. Typically, multiple disc brakes have a
quantity of wear spacers equal to the number of
discs minus 1. For example: a 450DBBS brake has 4
discs and 3 wear spacers. The exception to this rule is the 420DBBS that has additional ‘thinner’ spacers that will require four (4) adjustments. The number of wear spacers will dictate the number of adjustments before the brake requires complete disassembly for friction disc replacement. Spacers are removed to correct for wear. One set of spacers is removed for
each wear adjustment.
Figure 3
DBBS Brakes
EATON Airflex ? DBB 8110 Brake Assembly E-CLCL-TT001-E December 2012
12
Figure 4
4.2.1
To determine when adjustment is required, make sure the brake is engaged then measure the gap between the spring housing (16) and the pressure plate (14) as shown in Figure 5. Measure the ‘Y’ gap between the pressure plate (14) and the reaction plate (31), the ‘Y’ gap between the reaction plate (31) and the mounting flange (2) and the ‘Y’ gap between the reaction plates (31) as shown in Figure 5, 6, 7., 8 and 9. If the measured gaps meet or be outside (larger or smaller) the limits shown on Table 8 AND none of the friction discs are worn to the bottom of the wear groove or the step on size 50 brakes, adjust the brake. It is also recommended to check the DBBS components for wear as shown in Table 7.. If any wear limit has been reached or exceeded, that component must be repaired or replaced.
If a wear adjustment is not made, the brake torque
may deteriorate to the point where the equipment will not stop properly.
Remove, retain or support discs as needed so that they do not fall off the gear during maintenance.
Note
Prior to August 2012, multiple disc DBBS units were manufactured with solid wear spacers (29), requiring brakes to be fully disassembled in order to make wear adjustments. Multiple disc units manufactured from August 2012 and later, use the split wear spacers and adjustment can be conducted without full disassembly. Check the date code on your brake to verify the date of manufacture.
4.2.2 Wear Adjustment with Solid Wear Spacers
Note
A Procedures for adjusting a two disc brake are listed below as an example.
4.2.2.1 Disconnect the air supply lines from the brake. Wipe
down the brake and match mark all components from the mounting flange (2) to the cylinder (19) prior to disassembly. Match marking all components will ensure that the components are reinstalled in the orientation and location from which they were removed.4.2.2.2 While supporting the cylinder (19), loosen the
locknuts (18) ONE TURN AT A TIME and in an alternating (crosswise) pattern to prevent binding of the cylinder on the studs. Continue to loosen the locknuts until the force of the release springs (34) is relieved, allowing for access to the wear spacers (29). It may be necessary to push the reaction
plate(s) (31) away from the mounting flange so that the release springs can be moved to gain access to the wear spacers.
Note
Once the assembly is loose, the wear spacers (29) can be rotated to confirm that they are the ‘Solid Wear Spacers’ and the disassembly can proceed per 4.2.2.3 below. The split spacers are identified by the presence of a slot running across the thickness of the spacer. If the wear spacers have the slot, then they have been replaced with a split spacer kit and the DBBS can be adjusted without complete disassembly. See Section 4.2.3 for wear adjustment with split wear spacers. See figure 11 for an illustration of the split wear spacer.

Loctite#262 must be shaken prior to application.
Caution
Loctite #262 may irritate sensitive skin. Refer to the product label for safety precautions.
4.2.2.4 Remove the outboard disc (58), the reaction plate
(31) and the release springs (34) and set aside.
Note
For 3 disc brakes remove one additional disc,
reaction plate and set of springs during disassembly.
Note
For 4 disc brakes remove two additional disc,
reaction plate and set of springs during disassembly.
4.2.2.5 Slide the clamp tubes (12) and one set (layer) of wear
spacers (29) off of the studs. Reinstall the clamp tubes only. For all sizes of DBBS brakes clamp tubes (12) are placed over every stud (6).
4.2.2.6 Place the release springs (34) onto the clamp tubes
(12) and slide the reaction plate (31) onto the clamp tubes. Note
For 2,3 & 4 disc brakes, sizes 20, 25 & 38 DBBS, release springs (12) are equally spaced on 4 clamp tubes.
Note
For 2,3 & 4 disc brakes, size 50DBBS, release springs (12) are placed on every clamp tube.
4.2.2.7. Slide the second disc onto the gear.
4.2.2.8 Place the release springs (34) onto the clamp tube
(12) and slide the pressure plate/cylinder assembly onto the clamp tubes. 4.2.2.9 Lubricate the threads on the ends of the studs with
30 wt. oil or anti-seizing compound and install the locknuts (18), washers (17.) and the wear spacers (29) removed in 4.2.2.5. The wear spacers are “stored” under the locknuts for use after replacing friction discs (8). See Figure 10.
Note
It is recommended to dispose of the solid wear spacers and use split spacers when replacing the friction discs.
4.2.2.10 While supporting the weight of the cylinder/
spring housing/pressure plate assembly, tighten the locknuts (18), ONE TURN AT A TIME and in a crosswise pattern, until the spring housing is seated against the clamp tubes. Torque the locknuts to the appropriate value. See Table 4.
The locknuts (18) must be tightened gradually to prevent damage to the brake components.4.2.3
Wear Adjustment with Split Wear Spacers
Note
To determine the type of wear spacers (29) installed in the brake, refer to section 4.2.3.4 that directs to loosen the locknuts (18) until the force of the release springs is relieved. Once the assembly is loose, the wear spacers can be rotated to confirm that they are the ‘Split Spacers’. The split wear spacers are identified by the presence of a slot running across the thickness of the spacer. If the wear spacers do

not have the slot then they are solid wear spacers and the DBBS must be disassembled per 4.2.2 in order to make adjustments.
Be sure to follow 4.2.3.4 instructions complete to
prevent damage to the brake components
4.2.3.1
Disconnect the air supply lines from the brake. Wipe
down the brake and match mark all components from the mounting flange (2) to the cylinder (19)
prior to disassembly. Match marking all components will ensure that the components are reinstalled in the orientation and location from which they were removed.
4.2.3.2 Wear adjustment can be conducted without full
disassembly of the Multi-disc DBBS brake. The wear adjustment spacers are slotted to allow for easy removal with a chisel. See Figure 11. 4.2.3.3
Wear spacers shall be removed in complete sets only
(one from each stud location). Mark the spacers to be removed to avoid confusion during removal.
Removal of spacers in quantities other than complete sets (layers) will result in severe damage to DBBS components during reassembly and could cause the brake to not function properly.
4.2.3.4 Loosen the locknuts (18) one at a time and in an
alternating (crosswise) pattern to prevent binding of the cylinder on the studs. Continue to loosen the locknuts until the force of the release springs is relieved, allowing for access to the wear spacers. It may be necessary to push the reaction plate(s) away from the mounting flange so that the release springs can be moved to gain access to the wear spacers.
The locknuts (18) must be loosened gradually to prevent damage to the brake components.Caution
Remove discs as needed so that they do not fall off the gear during maintenance.
4.2.3.5 Using a narrow chisel wedged into the slot in the
wear spacer, pry the wear spacer until it fractures and is clear to be removed from the stud. Repeat for the remaining spacers in the set that is to be removed (one spacer from each stud position). See Fig 11.
Removing Split Wear Spacers with Chisel
Be sure to collect all wear spacers when removed. Spacers lodging in between brake components could prevent the brake from properly engaging or releasing.
4.2.3.6 While supporting the weight of the cylinder/piston
assembly, tighten the locknuts (18) ONE TURN AT A TIME and in a crosswise pattern until the cylinder is seated firmly against the clamp tubes. Torque the locknuts to the appropriate value. See Table 4.The locknuts (18) must be tightened gradually and evenly to prevent damage to the brake components.
4.2.3.7. Restore any piping or covers removed prior to
operating the brake.4.3
Friction Disc Replacement
Use only genuine, Airflex friction material. Use of material not of Airflex origin may result in
unpredictable brake performance and/or excessive wear of the brake components.

Loosen the locknuts (18) ONE TURN AT A TIME and in an alternating (crosswise) pattern until the spring force is relieved. Remove the locknuts, washers (17.) and wear spacers (if stored).
Caution
The locknuts (18) must be loosened gradually to prevent damage to the brake components.
Refer to Table 9 for power head weights before lifting the power head. Provide properly rated lifting devices. Failure to use the properly sized and rated lifting devices can cause equipment damage and personal injury. Note
The term ‘power head’ refers to the subassembly consisting of the spring housing, cylinder, and pressure plate.
4.3.5
Lift the cylinder, spring housing, and pressure plate off of the studs as an assembly. Set the assembly aside on a level working surface, with the cylinder facing down.
Note
If a stud (6) should happen to come loose, remove it completely and clean the threads on the stud and the threads in the mounting flange. Apply Loctite Primer Grade “T” to the stud Threads. After the threads
have dried, assemble to the mounting flange using Loctite #262. The end of the stud must not extend past the mounting surface on the mounting flange.
Caution
Loctite #262 must be shaken prior to application.Caution
Loctite #262 may irritate sensitive skin. Refer to the product label for safety precautions.
4.3.6
On multiple disc brakes, remove the reaction plate (31), release springs (34), clamp tubes (12) and the remaining disc(s)(58).
4.3.7.
Inspect the brake components for wear or damage. Replace as required. For wear limits of components, see Table 7..
4.3.8
Remove the socket head screws and friction discs or blocks and discard.
Note
It may be necessary to use heat to soften the Loctite to ease screw removal. Use a pinpoint torch, heating only the socket area of the screw.
4.3.9
Smooth the friction mounting surfaces of any burrs or raised areas with a course, flat polishing stone, and clean the tapped holes of any residual Loctite or other contamination. Check screw fit and chase the threads if necessary being sure to final clean the tapped holes of any residual contamination.Caution
Before installing screws, make sure that the screw threads and threaded holes are clean to ensure that the new screws will lock properly.
4.3.10 Position the new friction discs (friction blocks on the
50DBBS) on the mounting surfaces. Apply Loctite #262 to the threads of the screws (57.), install and torque the screws to 20 ft.-lb.
Loctite #262 must be shaken prior to application.
DBBS Brakes
Loctite #262 may irritate sensitive skin. Refer to the
product label for safety precautions.
Note
When replacing friction material, it is suggested that

4.3.12.1 Wear Spacers (29) are installed in sets onto each
stud. The number of wear spacers must be equal on
each stud.
4.3.12.2 Clamp tubes (12) are installed onto each stud and
rest upon the wear spacers (29).
4.3.12.3 Release springs (34) are installed over the clamp
tubes (12) as outlined in Section 4.2.2.6
The position of the release springs can vary with
different brake sizes. If unsure of assembly position,
consult Eaton Airflex Engineering. The springs on
either side of the reaction plate must be assembled
on the same stud, over the clamp tubes. Improper
assembly will result in cocking of the reaction plate
and uneven brake release. Refer to section 4.2 and
6.1 for wear spacer quantity.
4.3.13 Lubricate the threads on the ends of the studs with
30 wt. oil or Never Seez? anti-seizing compound.
