SPACE AND COST ISSUES RESOLVED WITH DLGF
FLAT RODLESS CYLINDER FROM FESTO
Festo already has the widest range of rodless
cylinders available, but it is broadening
customer choice even further with the
introduction of an outstanding new, clean
line variant. Called DLGF, the new rodless
cylinder is designed to significantly reduce
design time and cost in applications where
space is at a premium.
Rodless pneumatic cylinders are typically
used where mounting space is restricted.
They eliminate the protuberance of the barrel
of a standard pneumatic cylinder by coupling
the internal piston within the cylinder
barrel to the external carriage via an axial
slot. The piston and carriage run the whole
length of the barrel, with the air pressure
being retained by a seal running the entire
length of the cylinder. There is only a short
‘dead space’ at either end of the cylinder to
accommodate the end caps and cushioning
arrangement – saving nearly 50% of the
length of a standard piston rod arrangement.
The DLGF rodless cylinder from Festo has
been designed to further reduce the space
envelope and lower costs with award-
winning1 innovative design features.

It is suitable for light to medium loads and
features an ultra slim oval profile. Available
in stroke lengths of up to 1000mm, the DLGF
is available with piston areas equivalent
to diameters of 20, 25, 32 and 40mm. It is
perfect for applications where installation
space is at a premium, including pick-and
place, small parts transfer and circuit board
handling.
In developing the DLGF rodless cylinder,
Festo focussed on delivering high
performance at a very competitive price.
The DLGF uniquely offers PPS self-adjusting
cushioning, ensuring optimal damping
regardless of the mass being moved. This
saves setup time and makes processes
more reliable by eliminating excessive
shock loadings and vibrations that
can adversely affect machine
performance and product
reliability, as well
as generating
unnecessary
noise.
New sealing technology reduces air leakage,
delivering lower operational costs and longer
service life.
The DLGF saves designers a lot of time. It is
highly configurable, providing a wide choice
of supply port positions that enable piping
to be routed out of the way, increasing
mounting flexibility in tight spaces.
Shock absorbers can be specified or
fitted later if required.
