5 Cylinder Solutions for Tight Spaces

The position of each component on your equipment is critical to ensure optimal safety and performance. When space is limited for your hydraulic system, turn to the experts at RAM Industries!

RAM’s custom approach enables you to fit your machinery with hydraulic cylinders that will not only maximize your performance but will perfectly meet the specific space requirements on your machinery.


Many cylinder designs help maximize motion achieved in constrained spaces. RAM Telescopic cylinders and Piggy-back cylinders are two of the most common cylinders that provide space-saving benefits. RAM can also incorporate other unique cylinder design elements for your cylinders to save space on your equipment.


  1.  Telescopic cylinders provide a long stroke from a very compact retracted length. RAM manufactures telescopic cylinders with up to 5 stages. Depending on how gravity impacts your retraction, RAM can incorporate single-actingdouble- acting, or hybrid designs to ensure efficient performance.

  2.  Piggy-back cylinders have two cylinders welded or yoked together in opposite directions. This cylinder design can double the stroke available while maintaining consistent force for the full extension and retraction.

  3.  Increasing system pressure from 3000 PSI to 5000 PSI can provide better force production with higher pressure with a smaller cross-section.

  4.  Incorporating exotic metals can provide higher strength allowing a smaller cross-sectional size for mounts and barrels for larger diameter cylinders. Using stronger metals can allow savings on the overall diameter of your cylinder.

  5.  Utilizing unique internal components is another way to reduce cylinder length. Using a thread-on piston instead of a bolt-on piston can help you save on the overall length while maintaining strength.

RAM Industries always considers your overall application to ensure that cylinder strength is not compromised. The RAM engineering team has the expertise to work with you to find the right solutions that perfectly meet your fit and function requirements and maintain the reliability and integrity you expect.

Cylinder Port Flexibility

posted by RAM Industries Inc.    |   January 13, 2022 08:05

Hydraulic Cylinder Port Flexibility

Selecting a cylinder with proper ports and port placement is important to prevent stress on the cylinder during operation. Trust the experts at RAM to ensure your cylinder designs incorporate the right ports and port locations.

Hydraulic cylinder ports play a critical role in accommodating the fluid flow between the cylinder and the equipment. Ports allow fluid both in and out of the cylinder to achieve the linear motion produced by the cylinder. Restricted fluid movement through improperly sized ports or hydraulic hose binding can lead to pressure resistance.

Single-acting cylinders typically have one connection port at the lower portion of the cylinder body. This allows the oil to advance the piston rod and allow the oil to flow back into the hydraulic pump's reservoir when it retracts.

Double-acting cylinders perform with hydraulic fluid on both sides of the apron portion of the piston. They are equipped with two connection ports, one at the lower part, the other at the top part of the cylinder body.

RAM specializes in working alongside every customer to share ideas and gather critical information regarding each application's hydraulic cylinder fit and performance requirements. This collaboration ensures your cylinder design incorporates the ideal port type, size, and position.

Port Type

Ports contain standard thread dimensions to accept hydraulic fittings and hoses. There is a range of common port types available. The most commonly used ports include ORB or SAE (O-Ring Boss or Society of Automotive Engineers) and NPT (National Pipe Thread) ports. These ports are readily available in a large variety of sizes, shapes and materials.

Additional ports include JIC (Joint Industry Council), Code 61, Code 62 and Sandwich Plate. The application will often indicate which port option is best; however multiple port options may be suitable. For example, Code 61 and Code 62 ports are used in more robust and high-flow applications.

Port Size

Cylinder port sizes often range from 1/4 inch to 3 inches. They are typically referred by numbers from #1 to #48. In addition to cylinder size, the port size is essential to ensure an efficient flow rate from the hydraulic hose to the cylinder. The more fluid that needs to flow through, the bigger the port required. Using the correct sized port will prevent pressure resistance. The most common sized port used is #8, which is the equivalent of 1/2 inch hydraulic hose size.

Port Location

Cylinder port locations can be on any side of the cylinder head and cap end cover. Considerations for the ports' position include aligning the cylinder with the equipment design, ease of installation and servicing, ensuring optimal plumbing, and preventing binding or breakage points for hydraulic hose protection. Custom port manifolds can include specific hose locations on a cylinder or tie into the cylinder with additional control valves such as counterbalance valves.

With over 45 years of experience, you can trust the team at RAM to provide the optimal cylinder solutions specific to your equipment. RAM knows the ports on your cylinders can significantly impact the function and longevity of your cylinders and your equipment.

Six Points For Cylinder Seal Selection

posted by RAM Industries Inc.    |   December 9, 2021 08:05

Six Points for Cylinder Seal Selection

Seal selection is an important decision in your hydraulic cylinder design. Proper seal selection significantly affects the cylinder performance and longevity.


RAM's expertise in hydraulic cylinders ensures you receive cylinders that meet needs specific to your application. RAM's engineering team works with the experts at your company to fully understand the requirements for your cylinder's operation.


Six points for seal selection include:


1.       Pressure Rating

Selecting hydraulic seals specific to the operating pressure and potential pressure surges is vital. The appropriate seals will sufficiently maintain pressure and help prevent damage or leaking.


2.       Single or Double-Acting

Single-acting seals are designed for cylinders where pressure is applied from one side only. Double-acting seals are used in cylinders where pressure is applied on both sides. The configuration and type of seals on the piston is a factor in ensuring optimal cylinder performance.


3.       Operating Temperature

The cylinder’s operating environment can influence the material selection of your seals. Considerations include the temperature at cylinder startup and temperature during peak operation. Cylinder seals can be optimized from -40 degrees C/-40 degrees F to 200 degrees C/392 degrees F. Some industrial applications such as steel mills, plastic injection molding, and paint lines may require seals that accommodate even higher thresholds.


4.       Medium Used

Selected seals must be compatible with the internal fluid medium to ensure maximum efficiency and effectiveness. The most commonly used medium is petroleum-based oil. Other fluids include water-based hydraulic fluid such as water-glycol, bio-based oils such as vegetable oils, and petroleum-based oils with fire suppression additives.


5.       Velocity

Seal response within the cylinder can be influenced by the operating velocity of the piston rod during stroking. Slow cylinders can struggle with "seal stick." Reduced friction seals make them slippery and function more smoothly. High-velocity cylinders need seals that can keep up with the speed and temperature generated from the frequency of use.


6.       Longevity

Cylinder cycle frequency can determine the longevity required from the seals. A cylinder used once a day compared to one used 30 times an hour 24/7 may require more robust seals. Selecting the right seal based on the operation frequency ensures they will work reliably for the expected life cycle.


These factors impact hydraulic seal style, configuration and material composition.

Gooseneck Cylinders

Hauling heavy equipment is made easy with hydraulic detachable gooseneck trailers. Gooseneck cylinders showcase their strength in this application by doing the heavy lifting for you.

This lowboy trailer style is very common and versatile because of the ease in loading and unloading. Hydraulic cylinders make it simple and fast for the operator to detach, raise and lower the trailer from a truck when required.

Gooseneck cylinders are designed to lift the full load rating of the trailer. They also work to maintain a constant center of balance and keep the load secure during transport in any conditions.

Examples of RAM hydraulic cylinders used on gooseneck trailers include:

  • Gooseneck folding cylinders
  • Detachable gooseneck tongue cylinders

  • Hydraulic detachable gooseneck lift cylinders

  • Tower lift cylinders

RAM Gooseneck cylinders are double-acting and range from 5 inches to 12 inches in diameter. The most common size is 10 inches in diameter with a 4-inch shaft. A clevis-style mount is typically used on both ends and includes a heavy pin 2 ½ to 3 inches in diameter. A popular feature RAM provides is a drilled pin. This drilled hole allows grease to lubricate the connection between the pin, mount and the trailer giving extended life to the joint.

The majority of gooseneck cylinders operate in retraction, putting additional stress where the piston and shaft join. RAM uses high-quality steel and incorporates a set screw as a secondary locking device between the piston and the shaft to ensure they have the needed strength.

RAM considers operating conditions for all cylinder designs. In this application, high-quality wipers are used for aggressive scraping to remove material adhering to the shaft during transport. Corrosion resistant shafts and RAM’s two-part urethane paint process also provide additional protection.

RAM Industries has extensive experience building custom heavy-duty and reliable hydraulic cylinders for transportation applications.
