Double-acting hydraulic cylinders

D series double acting cylinders.pdf

Double-acting hydraulic cylinders D are suitable for situations that require force in two different directions. They are also suitable for cases where both controlled lifting and controlled lowering of a load are required. They are also ideal where it is necessary to reliably achieve a very fast return stroke when using long hoses.

An extended 3-year warranty is a given.

The unique design of the guide surfaces withstands lateral loads without binding.
Standard H – hardened inner cylinder surface with increased corrosion protection results in resistance to moisture and damage to the cylinder interior by dirt. This minimizes the possibility of seizure.
Standard S – piston wiper ring prevents oil contamination and extends service life.
The safety valve protects against damage in the event of accidental overpressure.
In combination with a suitable two-stage pump, it is possible to achieve very high performance.

DS - Standard double-acting cylinders

DU - Multi-purpose double-acting cylinders

Suitable for lifting and lowering work
Threaded holes in the bottom of the cylinder make it easy to mount to various devices
No pulling force can be applied with these cylinders.

Multi-purpose double-acting cylinder can apply both compressive and tensile force
Thread on the front side of the piston rod to transmit tensile force
External thread with cap on the circumference of the cylinder for mounting on various devices
Threaded holes in the cylinder bottom (as in DS version)
For lifting and lowering work or as a power element of various devices

SCOPE OF DELIVERY

Fixed pressure target on the piston face
Standard quick couplings for connection to the pressure oil source
Safety valve on the cylinder to protect the working area
