1 Function and application
The clamping cartridge 2 holds the c lamping rod 4 (with effective load) firmly in
any position.
Clamping the clamping rod 4
When the clamping cartridge 2 is
exhausted, a spring presses the
clamping jaws apart. As a result of
the clamping jaws being pushed
apart, the jaws are tilted on the
clamping rod 4.Theclampingrod
4 is clamped in a friction-locking
manner.

Pneumatically releas ing t he
clamping rod 4
When the clamping cartridge2 is
pressurised (supply port 1), a pis-
ton presses the clamping jaws to-
gether until the jaws are parallel to
each other. The holes in the clamp-
ing jaws then lie in an axis with the
clamping rod4.Theclampisre-

Manually releasing the c lamping
rod 4
• Scre w the supplied mounting
screw 9 (M5 DIN 912 or GÁ)in-
to the supply port 1 of the
clamping cartridge2.
This presses the clamping jaws to-
gether over the piston until the
clamping is loosened.

Note
The clamping cartridge 2 can be damaged when manually releasing the c lamp.
• Only screw the mounting screw9 into the supply port1 until the clamp is
released.
The clamping cartridge2 is designed for holding a clamping rod4 (in most c ases
a piston rod).
The clamping unit is intended for the following applications:
– Holding or c lamping the clamping rod4 in any position.
– Avoiding stroke movements:
– due to fluctuations in the operating pressure
– due to leakage on seals or tubing.
Note
Clamping in movement sequences (braking) is not permitted. Increased wear
leading to complete failure is possible.
• Make sure that the dynamic holding force is always less than the static holding
force.
If a pressure failure occurs (e .g. caused by an emergency switch off), c ontinued
use is only permitted after a subsequent functional test ( Operation). Except in
the event of sudden pressure failure, clamping may only be underta ken when the
cylinder is in the intermediate or end positions of the cylinder, referred to here as
the parking position.
• Only pressurise a clamped piston rod4
that is resting in a park position in chamber
(K
h
) on the stroke side.
This is to prevent the piston from moving to
a non-pressurised chamber when clamping
is released.
