NOTE: The dotted line on the static data chart shows
the force capabilities of the 1M1A-1 when attaching an
additional 0.5 inch pedestal, provided by the customer,
to the base of the air spring. If an additional pedestal is
not used, the air spring will behave as the solid line
depicts. Without a pedestal the rubber part will contact
the ground at the height of 2.1 inches and could cause
the rubber part to wear prematurely.
