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)

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)
