Work Supports 7250 psi max
Single and double acting

Automatically adjusts to proper height for
supporting workpiece. Prevents deflection
and vibration due to machining forces. May
also be used underneath clamps to back
up clamping force. More accurate, more
consistent, and much faster than screw jacks.
Precision sleeve around support plunger
holds it absolutely vertical while unlocked,
then locks it securely when fluid pressure is
applied. Plunger remains perfectly stationary
during locking. Far better accuracy and
repeatability than earlier segmented-collet or
sandwiched-plate work supports. Choice of
three actions:

Spring Extended
(Plunger floats then locks)
Plunger is normally extended by light spring
force. Workpiece’s weight depresses plunger
to proper height. Applying fluid pressure
locks plunger securely.
Threaded Body
pages 664-665

Fluid Advanced
(Plunger advances then locks)
Plunger is normally retracted for clear
loading/unloading. Applying fluid pressure
gently advances plunger to the workpiece,
then automatically locks it. Note: do not use
Threaded Body advancing plunger to lift loads.

Air Advanced/Extended
(Plunger floats or advances
by air pressure)
Plunger is normally retracted for clear
loading/unloading. Applying air pressure
advances plunger to the workpiece. This
allows fine tuning contact pressure using
a simple air regulator. Contact force may
Threaded Body be as light as a few ounces. Applying fluid 14
