Advantages of Aluminum Hydraulic Cylinders
Aluminum hydraulic cylinders work on the same hydraulic principles as steel cylinders: a piston in a barrel uses pressurized fluid to create linear force. The primary difference is material. Aluminum is chosen when lower weight and easier handling are priorities but you still need the published working pressure and tonnage ratings that Winshaw supplies.
Below we summarize practical benefits, typical uses, model families, and straightforward selection and maintenance tips to help you decide whether an aluminum model fits your application.
Why choose aluminum hydraulic cylinders?
Aluminum cylinders are notably lighter than steel equivalents with the same external dimensions. That weight difference delivers practical advantages:
- Portability: Easier to move, position, and remove during field work or maintenance.
- Operator ergonomics: Reduced handling weight reduces fatigue and speeds manual setup when cylinders are repositioned frequently.
- Corrosion resistance: Many aluminum alloys resist corrosion well; surface finishes further improve longevity outdoors or in corrosive atmospheres.
- Serviceability: Lighter assemblies are easier to disassemble, inspect, and reassemble for routine maintenance.

Common applications
Aluminum cylinders are commonly used where weight or portability matter: field maintenance, temporary lifting/jacking, and tasks requiring frequent repositioning. They are suitable whenever the working pressure and tonnage of the aluminum models match the application requirements.
How aluminum cylinders differ in practice
Beyond lower weight, choosing aluminum affects fixture design, transport, and the choice of handling equipment. Aluminum has different stiffness and strength properties than steel, so always confirm the published tonnage and pressure ratings for the specific model you plan to use.
Types of aluminum hydraulic cylinders
Winshaw offers multiple aluminum cylinder families to match application needs, including single acting, double acting, hollow, and failsafe lock-ring models. The published specifications below are provided by Winshaw and are preserved exactly as supplied.
- Single Acting Solid Aluminum Cylinders (HAS Model)
The HAS Model single acting solid aluminum cylinder has a working pressure of 10,000 PSI (700 bar) and capacities from 35 to 121 tons. These cylinders are single acting with spring-assisted return and have stroke lengths from 2.01″ (51 mm) to 12.01″ (305 mm). - Single Acting Hollow Aluminum Cylinders (HHA Model)
The HHA Model single acting hollow aluminum cylinder has a working pressure of 10,000 PSI (700 bar) and capacities from 20 to 57 tons. These cylinders are single acting, hollow, and spring-assisted return with stroke lengths from 2.01″ (51 mm) to 4.14″ (105 mm). - Single Acting Failsafe Lock Ring Aluminum Cylinders (HFA Model)
The HFA Model single acting failsafe lock ring aluminum cylinders come in capacities from 35 to 121 tons with stroke lengths of 2.01″ (51 mm) to 12.01″ (305 mm). They include a mechanical lock ring for extended mechanical load hold. - Double Acting High Tonnage Aluminum Cylinders (HRA Model)
The HRA Model double acting aluminum cylinders share the same working pressure, capacities (35 to 121 tons), and stroke lengths (2.01″ to 12.01″) as the single acting models. Double acting designs provide greater control and efficiency for many tasks.
Maintenance, handling and selection tips
Follow routine hydraulic maintenance practices: inspect seals, fittings, and bearing surfaces and check for leaks or damage on a schedule appropriate to your environment. Lighter weight can make inspections and temporary removal easier, but the inspection checklist is the same as for steel cylinders.

Choosing the right cylinder for your use
- Confirm required working pressure and tonnage and match them to the published model specs.
- Decide whether a hollow piston or solid piston better suits tooling or pass-through needs.
- Consider whether a mechanical lock (failsafe lock ring) is required for extended load holding.
- Check surface finish and corrosion protection if cylinders are used outdoors or in corrosive settings.

Quick selection checklist
- Required tonnage and working pressure — confirm against the model spec sheet (PDF).
- Stroke length and physical envelope — ensure stroke and installed dimensions meet your fixture layout.
- Do you need a hollow piston or mechanical lock for pass-through tooling or extended load hold?
- Field handling and transport — choose aluminum for repetitive manual repositioning when weight matters.
Short FAQ
- Are aluminum cylinders as strong as steel? Aluminum and steel have different strength and stiffness characteristics. Use aluminum where lighter weight and portability are priorities and the published aluminum model tonnage and pressure ratings meet your load requirements.
- Can aluminum cylinders be used outdoors? Yes; many aluminum alloys resist corrosion well, and appropriate surface finishes further improve durability in outdoor or corrosive environments.
- Where can I get service parts or repair guidance? Winshaw offers parts and repair guidance. See the repair guide linked above for troubleshooting steps and contact Winshaw for parts and service.
