Note:
The dotted lines on the static load curves shows
the force of the SK 37-8 with an additional 0.6
inch pedestal under the piston. This pedestal is
NOT provided by ContiTech. If this pedestal is
not used, the bellow will contact the ground at
a height of approx. 2.2 inch. This should be
avoided because it could cause wear at the
bellow. Minimum pressure for service without
pedestal is 45 psi.
