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 Hydraulic Cylinders - RAM Industries

posted by RAM Industries Inc.    |   December 9, 2021 08:00

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. Whether you have a concept or a design, our technical sales and engineering teams work with you to supply cylinders that precisely fit your equipment. This is one of many benefits of RAM’s custom engineered approach to designing and manufacturing hydraulic cylinders.

Contact the experts at RAM today to discuss your gooseneck trailer cylinder requirements.

Pneumatic Cylinder Solutions

posted by RAM Industries Inc.    |   September 9, 2021 08:00

Pneumatic Cylinders

RAM Industries designs and manufactures pneumatic cylinders specific to your unique applications. Industries that frequently incorporate pneumatic cylinders include material handling, packaging, agriculture, automation, entertainment, marine, transportation, food production and medical.

Pneumatic cylinders are powered using compressed air instead of hydraulic fluid. When lower power is required, these air cylinders are a reliable fluid power alternative to hydraulic cylinders. Pneumatic systems are known for having a longer operating life. They also have low maintenance requirements.

The RAM engineering team works closely with the experts in your operation to produce custom cylinders engineered for your OEM equipment requirements.

  • These cylinders are available as single-acting and double-acting cylinders using one or two ports to operate. Single-acting pneumatic cylinders can be configured with an optional spring return or extension for use in unique applications.
  • A range of barrel materials can be used for pneumatic cylinders, including stainless steel, aluminum and chrome plated on the inside barrel. These materials are corrosion resistant, which helps provide protection against moisture in the air.
  • Rod thread lengths can be produced specifically to your requirements in applications where a standard mount is not used, including non-standard thread sizes. Rod extensions can also be manufactured with non-standard lengths. 

RAM’s custom approach ensures your pneumatic cylinders provided easy interchangeability with existing cylinders and meet fit and performance requirements for existing and new equipment.

Reach out to RAM’s engineering department with your pneumatic projects so we can provide solutions that meet your specifications and expectations.

Double-Acting Cylinder Solutions

posted by RAM Industries Inc.    |   July 6, 2021 08:00

Double-Acting Hydraulic Cylinders

When gravity is not on your side, double-acting hydraulic cylinders provide the force required from either direction. As a result, double-acting cylinders are effective on applications that require precise control and faster extension or retraction, especially from a horizontal position.

RAM industries’ double-acting cylinder solutions are available on single-stage and multi-stage hydraulic cylinders. In addition, RAM’s engineering experts work with your team to ensure your cylinders perfectly meet your specifications and performance requirements.

RAM’s Double-Acting Telescopic cylinders encompass a complex design that involves additional sealing within the internal body of the cylinder to seal off the different stages. Passageways are machined into the internal components of the cylinder to allow for proper staging.

RAM’s standard Double Acting Telescopic designs include specially prepared chrome tubing, high-quality seals and high-strength internal components that can be easily serviced and replaced when required.

Customize the mounting options for your cylinders to ensure a perfect fit on your equipment.

With over 45 years as a leader in hydraulic cylinder design and manufacturing, trust RAM to provide your double-acting cylinder solutions!
