Tapped Holes
Mounting the brake by
drawing it into a housing or
cavity again provides the rigid
support in an area no larger
than the outside diameter of
the brake. It is used where
through-bolt mounting is
impractical.
Flange
Mounting flanges can be
attached to the base design
using the tapped holes
provided.
Since the mating spline (either the Warner
Electric splined hub or your splined shaft) is
smaller than the brake bore, either end of the
brake can be positioned against the mounting
surface when using through bolts. If a Warner
Electric conduit box is being used and the back
of the brake must be against the mounting
surface, a relief in the mounting surface will be
required to accommodate the conduit box
mounting plate. (See page 4 for details).
Hub Mounting Options
If the Warner Electric splined drive hub is to be
used, it can be mounted in either of the
following sequences:
Note: Full spline engagement contact is
required between the splined hub or splined
shaft and the splined brake disc. The disc
must be able to move freely on the hub.
Recessed Hub
Mounting the hub on the
driving member prior to
mounting the brake
allows the splined hub to
be recessed in the brake
bore for maximum space
efficiency.
Extended Hub
Mounting the hub on the
driving member after
mounting the brake allows
the splined hub to extend
beyond the brake where
space allows.
When the splined hub has been located on the
shaft with its appropriate key, tighten the set
screws to the following torque values:
Brake Torque
ERS-26 10 lb. in.
ERS-42 20 lb. in.
ERS-49 35 lb. in.
ERS-57 35 lb. in.
ERS-68 85 lb. in.
Loc-tite ® 242 may be applied on screw threads
to minimize chances of screws backing off
under severe vibration.
4. After the brake and hub are secured in place,
attach the DC power source to the brake
terminals. Feed the wires through the brake
insulator boots before attaching them. After
the terminal screws are tightened (torque to
15 lb. in.), slide the boots over the screws
and terminals to insulate the electrical
connection.
Either terminal can be connected to the + or -
side of the power source. If a Warner Electric
CBC-100 or other Warner Electric control is
used, follow the wiring instructions supplied
with the control.
5. Your ERS brake is now ready for its static
test. Apply the rated DC voltage to the brake.
It should disengage and the shaft should
rotate freely.
Your ERS Brake is now ready to run.
