In a single acting hydraulic cylinder, oil only acts on one side of the piston so it can only be mechanically moved in one direction
Single acting telescopic cylinders are the simplest and most common design. As with a single acting rod style cylinder, the single acting telescopic cylinder is extended using hydraulic or pneumatic pressure but retracts using external forces when the fluid medium is removed and relieved to the reservoir. This external retraction force is usually gravity acting on the weight of the load. This external weight must obviously be sufficient to overcome the friction and mechanical losses within the machine design even after the work portion of the machine cycle has been accomplished.
Double-ended hydraulic cylinders have a single rod with a centrally placed piston. The rod protrudes from both ends of the cylinder body. The double-ended hydraulic cylinder is commonly used as a steering cylinder, and they can generate force in both directions.
A double acting hydraulic cylinder is extended and retracted using hydraulic or pneumatic pressure in both directions.
The extension and retraction fluid supply ports on double acting hydraulic telescopic cylinders are usually located at opposite ends of the cylinder assembly. This additional complexity makes double acting telescopic hydraulic cylinders very expensive. They are usually custom designed.To accomplish the double acting feature, additional hydraulic seals are added to internally seal off the individual stages. In addition, internal air or oil passageways are machined so that as each stage completes retracting, a passage is open to supply the next stage with pressurized fluid to retract.
We offer sealing solutions for a wide range of applications, including: steel mill, petro-chemical, construction equipment, oil & gas, etc.
