FW Series
race overrunning and intermediate speed
outer race overrunning. They are usually
selected for inner race overrunning. Where
outer race overrunning is necessary, use
the AL..KMSD2 clutch coupling.
Typical Applications
FW clutch couplings accommodate
angular and parallel misalignment, are
torsionally stiff and can couple shafts of
different sizes.
For in-line shaft applications
Outer race overrunning—
intermediate speed
Inner race overrunning—
high speed
FW clutch couplings are comprised of an
FSO clutch with a Form Flex disc coupling. The Model FSO clutch can not
accommodate any misalignment, so a
coupling is always required for shaft to
shaft in-line mounting. The FW clutch couplings are designed for high speed inner
Increased clutch-coupling speeds are
possible with FSO clutches having steel
labyrinth grease seals.
C/T is ideal for applications with high
speed outer race overrunning and slow
drive speed.
Models 403 through 712 are equipped
with PCE sprags and are shipped from the
factory with Mobil DTE Heavy Medium Oil.
FW-752 through 1018 clutches are
shipped from the factory with Fiske
Bothers Lubriplate Low-Temp Grease.

Clutch
The FW Series clutch coupling is
designed for inner race overrunning.
Mount the clutch half of the unit on the
driven shaft.
FWW Series
C/T sprags are available in FWW series.
Increased clutch-coupling speeds are
possible with FSO clutches having steel
labyrinth seals.
Check key and shaft stress before
making final clutch or coupling selection
since this may determine maximum
allowable drive torque capacity.
The FWW Series clutch coupling is
designed for inner race overrunning.
Mount the drive coupling on the drive
shaft and the driven coupling on the
driven shaft.
Note: Mounting is reversed for C/T Series.
FWW-420 through 745 clutches are
shipped from the factory with Mobil
DTE Heavy Medium oil.
For in-line shaft applications
requiring low torque
FWW clutch couplings are designed
for applications where the torque requirement is low in comparison to the shaft
diameters. Both bore diameters in
coupling hubs are larger than clutch
bores in FW and FWW series.
FWW-755 clutches are shipped from the
factory with Fiske Bothers Lubriplate
Low-Temp Grease.
