Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal
injury to personnel.

The equipment covered by
this installation manual must be installed in
accordance with these instructions. Failure
to do so may damage the equipment and
void the warranty.

The ceramic versions of Warner Electric
UniModules are completely assembled
clutch/brake packages for out of box use.
They are engineered for easy installation, while
providing extra long life over standard units.
Technically advanced ceramic friction material
provides exceptional wear resistance and
enhanced performance making Ceramic
UniModule clutch/brakes ideal for high cycle
rate applications.

Ceramic clutch/brake combinations are offered
in two configurations. The "1020-C" has a hub
input and a male shaft output. The "2030-C" has
a male shaft extension for both input and out­put. These two configurations are offered with
various mounting accessories to make ceramic
friction faced UniModules adaptable to many
power transmission systems.

The 1020-C UniModules are designed to mount
to the face of a C-Face motor as noted in
Table 1.

The 2030-C UniModules are designed to mount
using a base mounting kit. This allows the
modules to be mounted as a separate drive unit
driven from the prime mover by V-belts, chain
and sprockets, couplings, timing belts and other
standard power transmission components.

Mounting to a C-Face Motor

1. A hardened key is provided with the
mounting hardware for Ceramic UniModules.
Insert this key onto the motor shaft. It is
recommended to stake the end of the
motor shaft keyway to keep the key from
moving out during operation.

2. Align the keyway in the bore of the
UniModule to the key in the motor shaft
and slide the unit onto the motor shaft.
The normal alignment of the module to the
motor will be with the wire exit/conduit
box in the upright (12 o’clock) position as
shown in Figure 1.

Do not hammer or force the
module into position. To do so may damage
bearings or cause the friction faces to shift out
of alignment.

alternately to ensure even alignment of the
module. Tighten them to 30-35 foot
pounds.

Do not tighten the two (2) clutch
rotor set screws to the shaft before tightening
the four (4) module tie-bolts. This could cause
a preload on the pilot bearing resulting in
premature bearing failure.

4. Next secure the clutch rotor and fan

assembly to the motor shaft by tightening
the two (2) setscrews as follows:

a. There are two (2) access slots on

either side of the UniModule. A long
Allen wrench can be used to tighten
the two setscrews (90° apart) which
secure the clutch rotor and fan
assembly to the motor shaft.

b. Alternately align each setscrew with

one of the access slots by rotating the
clutch rotor and fan assembly through
one of the side vents with a small
screw driver taking care not to damage
the fan. (Figure 2a)

ensure that any excess is wiped off before unit
assembly to avoid lubricant contaminating the
clutch or brake friction faces.

c. Using a torque wrench and long Allen

socket, tighten the two (2) setscrews
to: (Figure 2b)

3. Secure the Ceramic UniModule to the motor
with the four (4) long mounting tie-bolts
provided. Tighten the four (4) bolts

(Requires 5/32 inch Allen wrench)

• Size 180: 40-45 inch pounds
(Requires 1/8 inch Allen wrench)
