Description
Vacuum-assisted
lifting cylinder
DZH
Double-acting
40 mm/483 N
50 ... 200 mm
PPV: pneumatic cush
ioning, adjustable at
both ends
For the precise positioning of steel panels
Slim design – ideal for tight fitting spaces
in press systems
Non-rotating piston rod
Adjustable end-position cushioning at both
ends
Vacuum port in the end cap
With and without ventilation hole
With ventilation hole: when the piston rod
is advanced, the vacuum cuts off and the
steel panel can then be removed
Ejection cylinder

.: 0.6 Nm
60 ... 200 mm
PP: preset end-position
cushioning at both
ends
For ejecting pressed metal parts from the
press tool
Slim design – ideal for tight fitting spaces
in press systems
Compact design: both air connections are
on the piston rod
Fixed integrated piston rod, cylinder
housing performs the movement
Preset end-position cushioning at both
ends
With cylindrical and tapered mounting
attachment

matic spring
EGF/EG
Single-acting
25 mm/approx. 37 N at
2 bar, approx. 112 N at
6 bar
150 ... 300 mm
Extremely high load capacity due to
reinforced piston rod and extended piston
rod bearing
Prevents panels from vibrating or getting
stuck on the press tool
Constant force for piston advance and
return
Choice of mounting via a thread on the
mounting cap or a flange on the end cap
Two air connections either on the front or
on the side of the end cap
Tool lifting cylinder
DNC
Double-acting
50 mm/990 ... 1,178 N 50 ... 250 mm
PPV: pneumatic cush
ioning, adjustable at
both ends
For lifting form tools in presses
High load capacity due to reinforced piston
rod and flange plate on the mounting cap
Non-rotating piston rod
Enables the press profile to be changed, for
example in the case of mirror-image
pressed parts such as car doors
Space-saving assembly in the press tool
from above
Variable forward and return stroke
connections on both bearing caps
Speed regulation through a fixed restrictor
on the bearing cap and adjustable fixed
restrictor on the connection cap
