CLAMPING ACTION: Fluid pressure pushes
up plunger, pulling up a clamping stud inserted
through center hole. Spring or fluid return.
CENTER HOLE: Choose either threaded or
unthreaded center hole. Threaded version is
ideal for pulling/pushing a drawbar or replacing
a nut on a clamp strap. Unthreaded version is
useful when clamp is removed for workpiece
loading.
Installation Possibilities IMPORTANT NOTES: For operating
pressures exceeding 5000 psi, use a grade
8 stud or equivalent.
It is important to torque the lock nut used
sufficiently to prevent damaging the piston

Penetration of aggressive cutting lubricants
and coolants through the sintered metal
air filter into the cylinder’s interior should
be avoided by appropriate arrangement or
covering.
