ROEMHELD hydraulic cylinder block single or double acting, are made of high alloy steel, bronze alloy and special aluminum alloy. They can be installed in any position and have a maximum stroke speed of 0.25m /s, except for the block B1.542 and the hydraulic block B1.590, which have twice the piston speed of 0.5m /s. The ROEMHELD block does not leak when it is stationary. Minimum stroke leakage due to double piston seal.

ROEMHELD hydraulic cylinderDouble acting cylinder block:

Dual acting cylinders are commonly used for linear motion in all hydraulic operations. They generate force in both directions and can therefore be used to push or pull. This guarantees high functional safety as well as precisely calculated and repeatable times for the trip.

ROEMHELD hydraulic cylinder single-acting cylinder with or without spring return:

Single-acting cylinder blocks can be used for all hydraulically operated linear movements that do not require retracting forces or for which the piston is retracted by external forces. This function can be done with or without spring return, in both cases the piston stretches when pressure is applied to the cylinder. When it does have spring return, after the pressure is released, the piston retracts under the action of the spring force. The pressure spring must not only overcome friction, but also supply hydraulic oil back to the tank. In the absence of spring return, the piston must be retracted by external force after pressure relief. Since there is no pressure spring installed, this single-acting cylinder block has the same stroke as a double-acting version of the same length. If the cutting lubricant and coolant are likely to seep into the cylinder through the centered metal air filter, the exhaust hose must be connected and placed in a protected location.
