1 Function and application
The clamping cartridge 2 holds the clamping 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. The clamping rod
4 is clamped in a friction-locking
manner.
Pneumatically releasing the
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. The clamp is re-
leased.
Manually releasing the clamping
rod 4
• Screw 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-
2
gether over the piston until the
clamping is loosened.

Note
The clamping cartridge 2 can be damaged when manually releasing the clamp.
7
• Only screw the mounting screw9 into the supply port1 until the clamp is
4
released.
2
The clamping cartridge2 is designed for holding a clamping rod4 (in most cases
a piston rod).
The clamping unit is intended for the following applications:
6 – Holding or clamping the clamping rod4 in any position.
– Avoiding stroke movements:
8
– 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
2
leading to complete failure is possible.
• Make sure that the dynamic holding force is always less than the static holding
6
force.
8
If a pressure failure occurs (e.g. caused by an emergency switch off ), continued
use is only permitted after a subsequent functional test (
3
the event of sudden pressure failure, clamping may only be undertaken when the
cylinder is in the intermediate or end positions of the cylinder, referred to here as
4
the parking position.
• Only pressurise a clamped piston rod4
that is resting in a park position in chamber
(K ) on the stroke side.
h
This is to prevent the piston from moving to
a non-pressurised chamber when clamping
is released.
