Are you confident your cylinders are sufficient for the hydraulic pressure rating of your equipment? Off-the-shelf cylinders are typically designed to industry standards, but they cannot anticipate the operating conditions of all equipment. All internal componentry and critical points in your cylinder will face significant pressure. By working with our team, you can be confident your RAM hydraulic cylinders will perform reliably under pressure every time!

PSI, which stands for pounds per square inch, indicates the pressure rating for the hydraulic system. To calculate the pressure rating, you need to divide the force by the total surface area to get the system pressure.

The industry standard for pressure ratings has evolved over the years to 3000 PSI, although each industry and application may vary. RAM Industries designs and builds cylinders to match your particular equipment's pressure rating. RAM can manufacture cylinders with a rating up to 7500 PSI.

All components in the hydraulic system must be rated to the same PSI or higher. For a cylinder to be rated as 3000 PSI, all integrated parts and materials must also be at least 3000 PSI. For example, an integrated 2500 PSI counterbalance valve would not work for a cylinder to be 3000 PSI rated.

Communication is a valuable part of the relationship RAM builds with customers. Letting us know your desired system pressure and pounds of force, or your preferred bore size, helps our team provide a suitable solution for your machinery. The experts at RAM review every aspect of your hydraulic cylinder design to verify your cylinders will achieve optimal performance. As part of our full-service approach, the RAM team provides recommendations considering your equipment's operating environment to ensure safe and efficient operation.

RAM creates a design plan with the criteria and componentry for each cylinder we make. A standard template of engineering calculations takes all criteria from the design plan and performs safety calculations for all critical points in the cylinder. This template provides output with the safety factor as a percentage of equivalent force. Ensuring your cylinders meet the required safety rating is essential, especially where human safety is directly involved.

At RAM, we test every hydraulic cylinder at a higher pressure than the designated PSI to ensure reliable performance during pressure surges or spikes. Static systems may experience constant pressure, unlike dynamic systems with fluctuations or shocks to the equipment. Customers may request testing at higher ratings, such as one and a half times the operating pressure. We make sure all internal components match the test pressure so your cylinders can withstand the pressure on the field.

With half a century of experience, rely on the RAM name to manufacture hydraulic cylinders you can trust!

Whatever stroke length you require, RAM’s cylinder stroke options are endless! RAM Industries produces hydraulic cylinders with lengths that meet your precise needs, from extremely long to very short.

The difference between when a cylinder is fully open (extended) and in home position (retracted) is the stroke length. When determining the stroke required for your equipment, it’s important determine the max retracted center to center distance for your application. That will help identify if you have enough room to get the movement needed to get to the required extended length.

Many industries benefit from the length hydraulic cylinders can support. Some examples of equipment applications that utilize longer cylinders include axle moving cylinders in transportation, scoping cylinders, pump jacks or dog houses in oil & gas, and deploying slides on camper trailers.

Once you define the stroke required, consider the bore size to ensure the proper combination. This combination defines how far the cylinder moves and how much force it can produce. Cylinders with a bore size greater than 9 inches can support lengths up to 130 inches. If the bore size is over 20 inches, the stroke length is limited to 14 inches.

Designing your cylinder to precise stroke measurements helps reduce potential issues, such as:

• Stroke length lengths too long? Overtravel can cause interference with other components.
• Stroke lengths too short? Equipment can’t produce the required movement.
• Improper bore-stroke combination? Force production can be inadequate.

When there are restrictions on the closed length, RAM’s Telescopic and Piggy-back cylinder designs can help meet your needs to achieve the stroke required with a compact retracted length.

As a custom manufacturer, RAM establishes a close technical rapport with every client to share ideas and gather information regarding cylinder fit and performance requirements.

Custom cylinders allow you to define the necessary stroke value. RAM Industries ensures the cylinder design is specific to your movement requirements to provide reliable force and control.

In addition to the stroke, RAM always considers the working environment, seal selection, and material recommendations to ensure your hydraulic cylinders perform to your quality standards.
