Double-acting hydraulic cylinders deliver force on both strokes—extension and retraction—for high‑tonnage lifting, precision positioning, and repeatable maintenance tasks. Dual ports pressurize the piston and rod sides to speed the powered return, delivering faster cycle times and consistent accuracy. In horizontal pipe‑jacking, the hydraulic reset quickly retracts the piston to prepare the next section.
These cylinders and jacks combine high repeatability with smooth motion control and durable sealing. A wide choice of capacities, strokes, and mounting styles fits presses, machine tools, lifting and clamping setups, and push–pull applications. Pair with manual, electric, or air-driven pumps and modular control valves for single- or multi‑point operation.
The RRH-Series Double Acting Hollow Plunger Cylinder boosts speed with its double-acting design and adds versatility with its hollow plunger. Multiple safeguards—including a corrosion-resistant finish, a nickel-plated tube, a relief valve, and a plunger wiper—ensure maximum durability and safety.
For greater efficiency, the Kashon RAR-Series double-acting aluminum cylinders provide quick and regulated hydraulic retraction. The anodized aluminum body is portable and lightweight as well as corrosion resistant. The saddle and base plate are made of hardened steel for maximum durability.
Built without compromise, Kashon’s RR series double-acting cylinders deliver both the sheer resilience required for demanding job sites and the meticulous precision needed for high-cycle industrial operations
The HCG-Series, Single-Acting High Tonnage Hydraulic Cylinder engineered to offer exceptional durability and resist off-center loads.
The HCR double-acting high-tonnage hydraulic cylinder is ideal for heavy industrial applications. It features a sealed hydraulic design and a maximum lifting capacity of up to 1000 tons.
Available in numerous sizes, the Kashon CLRG series is a versatile, large-tonnage hydraulic jack. With a capacity of 50 to 1000 tons, its double-acting design ensures rapid lifting and lowering, while a safety valve provides over-pressure protection. We can outfit your specific tonnage and clearance needs with a single cylinder or a complete lifting system.
For applications requiring greater speed and precision, the HCRL-Series Lock Nut Hydraulic Cylinders introduces a double-acting design for rapid, fully managed hydraulic return. It builds on the HCL's core safety features and adds a standard tilt saddle for improved performance with off-center loads.
Double-acting hollow plunger cylinders feature a central bore through the piston and cylinder body and two hydraulic ports. Using a control valve, hydraulic pressure is directed either to the piston side or the rod side, so that the piston is driven both out and back in under power.
Threaded bars, anchors or bolts can be passed through the central bore. The cylinder then applies force directly to this element – in tension or in compression. The powered return stroke makes the cylinder independent of gravity or return springs and allows high cycle rates.
Active hydraulic power on both extension and retraction delivers usable force in both directions for pushing, pulling, clamping, and positioning.
Hydraulic retraction provides quicker, more precisely controlled return strokes than spring or load return—ideal for high-cycle, repeatable tasks.
Accurate control of position, speed, and force enables consistent results in presses, machine tools, lifting, and automated lines.
One cylinder handles both advancing and returning work, reducing components and simplifying systems that require alternating push and pull.
Two-port design integrates with manual, electric, or pneumatic-hydraulic pumps and control valves for flexible circuit design.
Rated 10,000 psi (700 bar) and designed to comply with ASME B30.1 for lifting safety, with noted product-line exceptions as specified.
Our engineering team specializes in designing bespoke hydraulic solutions tailored to your exact application requirements -- from unique tonnage ratings to specialized environmental conditions.

A double-acting cylinder develops force on both strokes. Hydraulic pressure is applied alternately to the cap end and the rod end through two ports, giving powered extension and a fast, precisely controlled retraction. This makes it ideal for push–pull duties, horizontal operations, and cyclic or automated processes where repeatable positioning, speed, and force control are critical.
For demanding lifting and positioning, the following features enhance performance and durability:
Start with the application and work backward:
Yes. Common customizations include extended strokes, alternative porting, special mounts (flange, trunnion, clevis), low- or high-temperature seal packages, marine-grade coatings, integrated valves (check/relief/flow control), and linear position feedback (e.g., LVDT or magnetostrictive) for advanced closed-loop motion control.
