Double Acting Hydraulic Cylinders
HDM custom designs and manufactures 1" to 5" bore double-acting hydraulic cylinders to meet the requirements of your application. Standard double-acting hydraulic cylinders accommodate operating pressures up to 3,000 PSI.
These cylinders, including jacks and rams, offer improved speed and efficiency, better movement control, greater versatility, and faster retraction than their single-acting counterparts.
Double-acting hydraulic cylinders apply force in both directions in a push-pull motion, allowing for extension and retraction under hydraulic power. They have two ports: one for pressurized fluid to enter and extend the piston, and another for retraction. Their balanced control and consistent force in both directions make them ideal for operations that require high precision.
Double-acting cylinders typically feature seals, rods, and pistons designed to handle high pressures. Their ability to perform work in both directions increases system efficiency.

- Automotive
- Chemical
- General Manufacturing
- Material Handling
- Metals
- Paper & Pulp
Applications include:
- Automobile Transport Carriers
- Conveyor Systems
- Doors
- Furnaces
- Paper Manufacturing Systems

Frequently Asked Questions
Have a question about Double Acting Hydraulic Cylinders? We are here to help.
What are the advantages of aluminum over steel in hydraulic cylinders?
Aluminum is significantly lighter than steel, making it easier to handle and install. It also offers natural corrosion resistance and good thermal conductivity, which can reduce wear in certain applications. However, aluminum is generally better suited for light to medium-duty applications compared to steel.
How do double-acting hydraulic cylinders differ from single-acting cylinders?
Double-acting cylinders apply hydraulic force in both directions, allowing for both extension and retraction under hydraulic power. Single-acting cylinders only apply hydraulic force in one direction, with retraction typically achieved by gravity or an external force.
What are the typical applications for double-acting aluminum hydraulic cylinders?
These cylinders are commonly used in applications where light to moderate forces is required, such as in material handling equipment, light industrial machinery, automotive lifts, mobile equipment, and medical devices.
What is the maximum pressure rating for aluminum hydraulic cylinders?
Aluminum hydraulic cylinders typically handle pressures up to 3,000 psi, though this number can vary depending on the specific design and application. They generally have lower pressure ratings than steel cylinders, which are better suited for high-pressure environments.
How does aluminum handle wear and tear compared to steel or cast iron?
We will begin in this chapter by dealing with some general quantum mechanical ideas. Some of the statements will be quite precise, others only partially precise. It will be hard to tell you as we go along which is which, but by the time you have finished the rest of the book, you will understand in looking back which parts hold up and which parts were only explained roughly.
Can hydraulic cylinders be used in high-temperature environments?
Yes. Properly specified Hydraulic Cylinders can be operated in high-temperature environments when customized for high-temperature applications.
What maintenance is required for double-acting aluminum cylinders?
Regular inspection of seals, rods, and ports for wear and tear is essential. Ensure proper lubrication, check for fluid leaks, and monitor for corrosion. Cleaning the exterior and ensuring the cylinder operates within its pressure and temperature limits will extend its life.
What customizations can be made for stroke length and bore size?
Stroke length and bore size can be tailored to the specific requirements of an application. Longer stroke lengths provide more piston travel, while larger bore sizes deliver greater force output. Customization allows the cylinder to be optimized for the desired load and motion.
Are aluminum hydraulic cylinders suitable for outdoor or corrosive environments?
Yes, aluminum’s natural corrosion resistance makes it suitable for outdoor and moderately corrosive environments. Anodized coatings or other surface treatments can further enhance its durability against corrosion, especially in marine or chemical environments.
How do I choose the right seal material for different fluids or temperatures?
The choice of seal material depends on the hydraulic fluid being used and the operating temperature. For example, Viton seals are excellent for high temperatures, while Nitrile or Buna-N seals are suitable for lower temperatures and standard hydraulic fluids. Consider the fluid's chemical properties and operating conditions when selecting seals.
What are the most common causes of failure in double-acting aluminum hydraulic cylinders?
Common causes of failure include fluid leaks due to worn seals, rod or cylinder barrel damage from excessive loads or contaminants, and corrosion in harsh environments. Operating outside of pressure and temperature limits can also cause premature failure.
What mounting options are available for these cylinders?
Custom mounting options include clevis mounts, flange mounts, trunnion mounts, and threaded or spherical rod ends. These options allow for flexibility in installation based on the application’s configuration.
Can aluminum cylinders be used in heavy-duty industrial applications?
While aluminum cylinders are best suited for light to medium-duty applications, they can be used in some heavy-duty situations if properly designed and reinforced. However, steel or cast-iron cylinders are generally more appropriate for heavy-duty industrial applications due to their higher strength and pressure capabilities.
How does the weight of an aluminum cylinder compare to a steel one for the same capacity?
Aluminum cylinders are significantly lighter than steel cylinders for the same capacity, typically weighing about one-third as much. This makes them easier to transport and install, especially in mobile equipment and applications where weight is a critical factor.
What are the lead times for custom aluminum hydraulic cylinders?
Lead times vary depending on the complexity of the customization, manufacturer capabilities, and current demand. Generally, lead times can range from a few weeks to several months. It's best to consult with the manufacturer for an accurate estimate based on your specific requirements.
