Technical Data
Cylinder with Rod Lock
Function on pressure loss
The piston rod lock can be used in all material handling
systems where controlled fastening or positioning is required.
Additional measures are required for use in safety-related
applications (refer to EC Machinery Directive).
The piston rod cylinder with brakes is suitable for use in
safety-related sections of control systems. The piston rod lock
is also suitable for use as a pressure-loss brake for cylinders
with suspended loads, for example. Piston rod can be held in
position for long periods even with alternating loads, fluctuating
operating pressure or leaks in the system. The signal air to the
lock unit can be connected directly to the air system or to the
supply air for the valve controlling the cylinder in question. For
controlled on/off operation of the lock unit, a separate valve,
with large exhaust flow capacity, is used.
Clean and compact design
The front end piece and lock unit form an integrated block,
keeping the length of the structure short. The design is easy
to clean, sealed and waterproof. The exhaust air from the
lock unit can be removed by replacing the filter unit with a
connector and hose. This is an advantage in terms of cleaning
or when environmental factors are important.

Note!
If a rod guidance module is to be fitted to the brake and the cylinder, as the piston rod extension (WH dimension) is not in
accordance with the ISO standard, the piston rod must be extended to provide the same WH dimension as for the cylinder
itself.
Cylinder piston rod material must be made in steel or stainless steel chromium plated.
