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.

Hydraulic Cushioning Cylinder Solutions

posted by RAM Industries Inc.    |   August 4, 2021 08:05

Hydraulic Cylinder Cushioning

Reducing the speed of a cylinder piston at the end of the stroke can be critical in some applications. RAM can incorporate hydraulic cushioning as part of a cylinder’s design. This feature can help reduce the stress on cylinder components and lesson vibration conveyed to other parts of equipment when operating at full force.

Careful evaluations by our experienced engineering staff determine the exact criteria to achieve the appropriate flow reduction. Factors that are evaluated include:

  • Maximum load that needs to be decelerated
  • Inertia and mass of the structure
  • Oil volume used in the application
  • Pressure rating of the equipment
  • Cycle time and frequency 

RAM’s engineering and machining expertise is demonstrated through the automated machining incorporating hydraulic cushions in our cylinders.

Holes are machined into the barrel, according to the cylinder design, to achieve the appropriate deceleration. Strategically placed port pass piston seals correspond to the hole locations to facilitate the restriction of oil flow. The hole location, number of holes, and piston seal placement and sizing are critical for every inch of motion. Hydraulic cushioning can be configured on both the extension and retraction ends of the cylinder.

RAM offers a few different standard cushioning configurations based on the applications the cylinder will be used on.

  • Basic applications requiring cushioning can use a design with two to four holes. A port block provides an oil channel to connect the multiple holes.
  • Applications with frequent or faster cycle time requirements may require a more complex configuration using multiple holes on the entire circumference of the barrel. An exterior steel tubing connects the internal oil channels and acts as an oil passage chamber to the port. This design allows for higher velocity cushioning and enables the cylinder to respond at a quicker rate.
  • Heavy-duty applications often use an internal configuration for cylinder cushioning. In this design the gland is machined with a precise chamber that forms a tight tolerance with a solid sleeve on the piston. A spud can also be incorporated on the end of the piston with a tight tolerance chamber in the cylinder base for double-ended cushioning.

Could your equipment benefit from the smoother stopping provided by hydraulic cushioning?

Contact the RAM team to discuss how we can incorporate hydraulic cushioning into cylinders for your projects.
