PB-500 Primary Brake Normal
Duty Pin Drive Armature
Installation Instructions
A. Installing the Conduit Box
Please follow instructions supplied with conduit box.
B. Mounting the Magnet
The brake magnet is mounted to a stationary machine
member by a flange. Extreme care must be taken in
selecting the location for the mounting of the magnet.
Proper positioning is very important for the unit to function
correctly.
1. A pilot diameter on the mounting surface is essential
to hold the magnet within the required tolerances.
(Figure 1)
2. A machined pilot diameter is provided on the magnet
mounting flange (refer to illustrations) to aid in the
proper positioning of the magnet.
3. Once the mounting surface has been prepared,
the magnet is bolted in place with capscrews and
lock-washers. (Figure 2)
Figure 1
Figure 2
Figure 3
C. Assembling the Armature Hub
Assemble the armature to the armature hub with the
autogap mounting accessory. Refer to Figure 4. The hub
is reversible. The side on which the armature is mounted
will depend on the direction in which the taperlock bushing
must enter.
The autogap assembly is a double spring device which
allows for automatic armature clearance and adjustment
for wear. The smaller or conical spring pushes the armature
from the rotor face, leaving the gap of about 1/32 inch,
while the straight spring automatically follows up for
wear. This combination maintains maximum performance
efficiency throughout the life of the unit.
4. Use a dial indicator to check the unit for concentric-
ity and squareness to the shaft. The unit should be
concentric within .010 T.I.R. and square within .006
T.I.R. (Figure 3)

Step 1
Place straight springs over armature bosses on back
side of armature. (Figure 5)
Step 2
Place armature hub over straight springs.
Straight springs must fit into
the grooves in armature hub. (Figure 6)
Step 3
Compress conical spring against retainer ring by sliding
detent spring towards head of pin. (All 3 pins) (Figure 7)

4. Securely fasten the armature assembly to the shaft
by alternately tightening each setscrew. During the
tightening process, the bushing should be tapped
lightly to make certain it seats-in properly.
Step 4
Insert assembled drive pins through armature hub and
straight springs and into the threaded armature bosses.
Apply grade “AA” Loctite Sealant on drive pin threads.
(Figure 8)
Step 5
Tighten drive pins until shoulders of pins are against
face of armature bosses. Since threads are class No. 3
fit, pins may seem to bind.
Step 6
Compress the retainers against the armature hub and
check to see that the armature hub is held tightly to the
armature bosses.
Note: This position must not be disturbed during
completion of assembly. (Figure 9)
Figure 9
Figure 8
Figure 10
D. Mounting the Armature Assembly
The armature and armature hub are mounted on the
shaft with a taperlock bushing. All parts must be clean
and free from burrs and chips before assembling.
1. Place the bushing into the hub and insert the key.
The key is a side-to-side fit and should not contact
the top of the keyway.
2. Insert the locking setscrews into the bushing and
slide the assembly onto the shaft.
3. Place the face of the armature approximately 1/32”
from the face of the magnet. Once this gap is set, it
will be automatically maintained throughout the life of
the unit. (Figure 10)

C. Assembling the Armature and Hub
Scan to watch!
Setting the Autogap for a Heavy Duty Clutch Coupling
or Brake in sizes 500 & 650
https://p.widencdn.net/mqwdke/V-0100-WE
The heavy duty units contain spline drive armatures and
hubs. The armatures are shipped with a built-in autogap
spring accessory. This device automatically maintains a
gap of about 1/32” between the armature and magnet
faces for the life of the unit.
Follow these instructions to assemble the armature and
splined hub.
Step 1
Place the splined hub on a flat surface. The extended
portion of the hub, where the set screw holes are locat-
ed, should be down.
Step 2
Check the detent ring in the armature assembly to
make sure it is centered evenly around the spline. This
ring moves freely, but it should be centered for easier
assembly of the hub.
Step 3
Holding the armature with the segmented side up, press
the armature onto the splined hub. This is most easily
done by applying firm back-and-forth pressure. (Figure
4)
Step 4
Push the assembly up against the retainer ring.
Figure 4
Figure 5
D. Mounting the Armature-Hub Assembly
1. Slide the armature-hub assembly onto the shaft
until the armature face touches the magnet face.
2. Move the assembly back to allow a gap of about
1/16” between the two faces.
3. Secure the armature-hub assembly in this posi-
tion by tightening the two setscrews in the hub.
4. Check the assembly by pressing the armature
into contact with the magnet face and then
releasing it. The armature should spring back
about 1/32”. This gap will be automatically main-
tained throughout the life of the unit. (Figure 5)
