DE-STA-CO Output Overload Clutches Type F, FC, S, C, D, FC-SD, C-SD - Manual (Page 9)

CAMCO CLUTCHES are precision assemblies
and should not be modified. Modification of the
clutch will VOID THE CAMCO WARRANTY.
APPLICATION RECOMMENDATIONS
1. Clutch operation in dusty or corrosive envi-
ronments may require special preparation.
Contact CAMCO for special modifications.
2. On applications other than the output of a
CAMCO Index Drive, clutch speeds must
not exceed 100 RPM.
3. High humidity, contaminants, or wash
down applications may require special
protection. If rust forms within the clutch, it
may act as a solid coupling and will not
release under overload conditions. Lubri-
cate every six months or more frequently
as the application requires.
Caution: Lubricate the spring pockets with
a light film to grease. Heavy lubrication of
the spring pocket may lock the plunger, due
to hydraulic pressure, preventing clutch
disengagement.
4. Use bronze bushings on sprockets, dials,
gears or pulleys when used at the high end
of the speed range (100 RPM) to reduce
wear. Special bronze flange plates are
available.
5. Clutch couplings require accurate shaft
alignment of .003" TIR. Insure that a clear-
ance gap is maintained between the body
and the drive plate around the full circum-
ference to the clutch (Type FC, C).
6. Use flange mounted clutches and clutch
couplings whenever possible. These
models provide superior mounting reliabil-
ity (Type D, F, FC).
7. Dowel pins should not protrude from the
drive plate or driven members, as they may
lock against the adjacent surface.
8. Do not operate without the detector limit
switch, electrically disconnecting the prime
mover (motor), as galling of the contacting
surfaces may result.
9. On high inertia applications, braking the
prime mover is recommended, in the dwell
cycle of the INDEX DRIVE, to minimize over
travel.
10. CAMCO recommends using limit switches
with rated travel not exceeding .008" for
actuation.

11. The torque required to re-engage the clutch
is usually 25% of the rating. Contact
CAMCO for special design, anti-friction
materials if the clutch is to be used with
very low torque settings.
12. Never use the clutch with a torque setting
close to the calculated operating torque.
Actual torques may be higher. Torque
spring tolerances and coefficients of friction
vary with temperature and application.
Allow 130% (1.3 service factor) when
applying a CAMCO clutch.
