Axial clamp seals
The SKF axial clamp seals are designed for
large and very large diameters and are
eminently suitable as secondary seals for
applications where otherwise the primary seals
would be subjected to excessive quantities of
particulate contaminants or water. The seals
do not rotate but seal axially against a rotating
counterface.
These SKF axial clamp seals are made of
appropriately profiled strips of non-reinforced
nitrile rubber which are held firmly in place by
stainless steel screw-type clamps. They are
available in the diameter range 150 to 4.600.
The standard range of axial clamp seals
basically comprises seals intended for inchdiameter
seatings. However, as normally the
seals are mounted with an approximately
25 mm gap between the ends, they may be
used for appropriate metric-size seatings. In
case of doubt, please contact the SKF
application engineering service.
SKF axial clamp seals are produced in three
different designs:
CT1 design
Axial clamp seals of the CT1 design (fig 96a)
have a flat face sealing lip and are held in
position by a screw-type clamp. The maximum
permissible axial displacement (operating
interference) with respect to the counterface is
+2,4 mm.
CT3 design
The seals of the CT3 design (fig 96b) differ
from those of the CT1 design only in the form
of the sealing lip. This is again flat but is provided
with annular grooves. These serve to
trap contaminants which may have started to
penetrate the lip/counterface contact. The
maximum operating interference for these
seals is +4,8 mm.
CT4 design
Axial clamp seals of the CT4 design (fig 96c)
are extra wide and have a double clamp. The
maximum operating interference is + 4,8 mm.
The sealing lip is flat as for the CT1 design.
