HYDROPNEUMATIC CYLINDERS
As fast as a pneumatic cylinder and as strong as a hydraulic one
As fast as a pneumatic cylinder and as strong as a hydraulic one
Pneumo-hydraulic cylinders integrate two components in a single actuator: a pneumatic cylinder and an air/oil pressure intensifier.
The pneumatic cylinder is located in the lower part of the unit and allows for rapid approach to the workpiece.
The air/oil intensifier is located in the upper part of the unit and allows the pressing of the piece with high force (up to ten times greater than the force that would be obtained with an air cylinder of the same bore).
Pneumo-hydraulic cylinders can replace hydraulic cylinders, eliminating the need for a dedicated hydraulic power unit.

Compressing
With 2 models and 9 sizes (thrust force from 5 kN to 419 kN) the pneumohydraulic power units of the AP and AX series offer high productivity at low costs.
They use compressed air as the only power source.
The approach stroke is completely pneumatic, fast, efficient and inexpensive.
Once in contact with the piece, the ingenious air-oil multiplier system develops the force necessary for the actual pressing.
Pressings, fittings, deformations, assemblies.
Operations that the cylinder performs easily, efficiently, combining the best of pneumatic and hydraulic technologies.
RELIABLE
High quality hydraulic and mechanical seals: these cylinders are built to last.
PRODUCTIVE
With pneumatically controlled approach and return and hydraulic pressing stroke, they guarantee reduced cycle times for unrivaled yield.
REDUCED CONSUMPTION
The pneumatic/hydraulic separation limits consumption to the pressing phase only, only when needed.
VERSATILE
With 2 models and 9 sizes (with thrust force from 5 kN to 419 kN) it is easy to find a cylinder to fit your application.
The hydropneumatic cylinders of the AP series have an linear structure.
The pneumatic part for approaching the piece and the hydraulic part for executing the pressing stroke are in fact placed on the same axis.
Simple and economical, they are the right choice when there are no particular problems of space.
The hydropneumatic cylinders of the AX series present the same technical and functional concept as the AP series.
Thanks to their compact size, they can be used when small dimensions are needed.
Their peculiar shape allows longer approach and working strokes, compared to the AP series.
The AX version can also be equipped with the BDC and TDC mechanical adjustment device (code XR).
The UP cylinders only carry out the working stroke, when the approach stroke is not necessary. They consist of a hydraulic multiplier that allows immediate use of force.
The characteristics of use are:
The bleed valve allows residual air to flow out of the hydraulic circuit.
By connecting a pressure transducer it is possible to detect the pressure / force of the working stroke.
It allows you to top up any hydraulic fluid by simply unscrewing the filling cap, without the aid of pumps for easy maintenance.
It indicates the quantity of hydraulic fluid circulating in the power group.
Integrated shock absorber for slowing down the rod stroke in the last 10 mm of the cylinder return stroke.
It protects the integrity of the cylinder and of the structure on which it is installed, especially in the presence of high return speeds and high work cycles.
The device limits, with centesimal precision, the excursion of the front piston rod.
This device, with manual adjustment, allows to preset the lenght of power stroke.
It allows the unit to be fixed to the structure.
Allows easy fixing of the mold to the cylinder rod.
It converts female (standard) thread to male.
Radial coupling device for fixing the mold.
To interface with the stem of the press, it increases its length.
For units in horizontal and vertical working position with rod upwards.
Complete with bracket, anti-rotation rod, guide bushing and bushing cap.
