Series 450 -453 DOUBLE ACTING CYLINDER, Ø 32 to 100 mm
Type: PES-DM WITH STATIC ROD-LOCKING DEVICE
Complying with VDMA 24562-AFNOR-ISO 6431 standards
GB
Equipped for magnetic position detection
APPLICATION PRINCIPLE
The static rod-locking device with or without manual override is fitted to
series 450 and 453 PES type cylinders with profiled barrel or tie-rods. It is
designed to hold the rod of the cylinder under load in the extended or retracted
position in the event of air pressure or power failure during machine opera-
tion. The rod-locking device acts mechanically on the cylinder rod. It is
unlocked when pressure is applied.
Advantages
Easily accessible and quick-to-operate manual override (3/4 turn).
●
● Possibility of integrating the following options associated to the manual
override:
- Integrated rod-lock pilot control.
- Detection (magnetic or electro-mechanical) of the position of the manual
override.
- Cylinder startup interlock system (Ø 80-100 mm).
Simple adaption. The compactly sized rod-locking device has approxi-
●
mately the same dimensions of a standard cylinder.
● Possibility of mounting to specially designed cylinders (with overlength
piston rod) complying with VDMA-ISO6431-AFNOR standards.
Holding of the piston rod in the end-of-stroke position: with rod extended
●
or rod retracted side.
● Holding in position of the maximum allowable cylinder load without creeping.
● Bi-directional action.
Optional mounting position.

OPERATING PRINCIPLE
■ NO PRESSURE ON STATIC ROD-LOCKING DEVICE (rod locked)
No pressure is transmitted to the locking pistons (1). The springs (3) apply an axial
force onto the two jaws (2) which clamp against the rod, holding it secure.

■ ROD-LOCKING DEVICE PRESSURISED (rod unlocked)
The pressure exerts a force on the 2 pneumatic pistons (1) which come into contact with
the two jaws (2), clamping them together. The 2 jaws no longer exert any force on the
rod which is free to move.

Actuating the manual override (4) by a ¾
turn makes the piston (5) come into contact
with the two jaws (2), clamping them to-
gether. The 2 jaws no longer exert any
force on the rod which is unlocked.
Caution: After having operated the
manual lock-up override, it must always
be returned to its normal operating po-
sition (rod lock "activated") by a trained
and qualified person before starting up
the system again.
